Javascrip have animation... or are you talking about the one function, reguestanimationfreame?Javascript animation works much different than CSS animation. It's possible to alter stylesheets with Javascript, but it's complicated and almost always not worth it, especially for something like animation.
-
I don't understand that?!?!?!?!? WHAT IS THE BAD PART ABOUT JAVASCRIPT!?!?!?!? ... To me... it's prefect... I guess cause I'm just getting into the program world, and JavaScript alone with a few other language I'm studying.. I don't know much yet to really say that... but still to me, JavaScript is awesome as it is. other language have been built on top of JavaScript; for a lightweight language that's powerful.What about svg's animation? SVG been around a lot longer then canvas, and it just doesn't make sense to me for how choppy the animation is... a least in my browser.the site and wiki for coffeescript seem to cover your second questionhttp://coffeescript.org/http://en.wikipedia.org/wiki/CoffeeScript regarding the first question, I guess it depends. I haven't used it, but then I like Javascript the way it is, good and bad. As a developer, I focus on enhancing the good parts and filtering out the not so good parts. but you can google for blogs and see what the pro and cons are for yourself.https://www.google.com/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=opinions%20on%20coffeescript&safe=off

going through the reference area. Wanted to drop a question. I wasn't going to ask this, but it been on my mind. What do you guys think of coffeesscript? And what is coffeScript?
-
... but, that's how I feel...Yeah, I didn't read any of that. You said something about not liking it when authors try to inject humor or personal stories or go off topic, right?

I understand. It act as an Object's, or in apply case, as an Array's method. Thank you, if I have read more carefully, I would have notice that... probably not... I don't know.Note the word "as". It is a simile. It executes the function as if it were a method of the object. It does not actually make it a method of the object.I doubt you'll understand this, because you seem to get into things you don't understand yet, but specifically what it does is execute the function in the scope of an object.
-
Thank, you thescientist.1) yes2) yes3) yes

With call() or apply() you can set the value of this, and invoke a function as a new method of an existing object. <~~~ I copy and paste this off w3s tutorials function section; Invocation page. If no then what does it mean/saying?No.
-
I'm just bewildered...

What is wrong with me experimenting? This is for practice and discovery. On that note://Original code: var add = (function () { var counter = 0; return function (x) {return counter+=x}})()add(10);add(15);document.getElementById("demo").innerHTML = add(20);//What I'm trying to do; there must be away to do it like this:function add(x) { var counter = counter || 0; function count(x) {return counter+=x;} return(count(x));}add(2);add(2); -

This is for (What I want to do) thing... Please take no offense to that, what I'm basically saing is that I came across an example, that use an if statement in place of the ternary I put in there, I put in the ternary cause I wanted to, as I was trying to figure out the correct logic that should be apply to these ternary to work. I though of other option, as in switch statement, and else if... switch statement would win if this was a real application... really a switch statement in another function would win to refer to it... or better yet the || logic... Why did you write that... now I have to:why are you over complicating it? Do you even know how a simple ternary operator works? Both your examples are extremely convoluted and impractical for a real life application (and from what I can see won't even work). As we keep saying, keep it simple until you understand the language and know what you're doing at a basic level first.
function checkSecretWord(guess){ var isCorrectGuess = guess === 'w3schools' ? 'Correct' : 'Incorrect guess, try again'; return isCorrectGuess;} console.log(checkSecretWord('mdn')); //logs 'Incorrect guess, try again'console.log(checkSecretWord('microsoft')); //logs 'Incorrect guess, try again'console.log(checkSecretWord('w3schools')); //logs 'Correct'function checkSecretWord(guess){ var isCorrectGuess = guess; var is = "";(isCorrectGuess === 'w3s') ?

What I mean is, your bless if you are born with (refer to signature that will refer you to picture), that you are only born with that, or something doesn't manifest from that... Your lucky.I just see it as more practice. When I start writing code that I'm going to use for application; robust is the goal... The main goal is to get it to work, the goal after that is to make it as robust as possible. As someone said to me on this forum, I took that that to value and go by it as a philosophy to programming, and go by it.... No more, must get back to learning. BYE! -
question 1) So if the variable x is going to hold a string value down the line. When declare, it'll be good practice to initialize it with a empty string value <-- Is that what you are saying?question 2) do this for only primitive values?question 3) Or both primitive, and composition values? Composition; for object {}, and for array [], and even for function... maybe not for function .Please answer all with yes or no, and if other please put at bottom of the replies which should be either yes or no.... <~~~ I hope this isn't seem as demanding. I'm just making sure of clarity for my sake.it's also a good practice to initialize your variables to a default value, ideally one indicative of the data type it's going store, especially in the case of a loosely typed language like Javascript.
-
Thanks Ingolme.Because if you didn't initialize it as an empty string the result will start off saying "undefined" and some browsers will throw an error message "text is not defined"

I like to alter the code sometimes when I go through the tutorial; as I am going through w3s js tutorial. And reading books on js, and etc.
(1 == 0) ? (a = "yes: 1 == 0") : (1 < 0) ? (a = "yes 1 < 0") : (1 <= 0) ? (a = "1 <= 0") : (0 >= 1) ? (a = "0 >= 1") : (a = "none of thee preceder"); console.log(a);var x = undefined, y = x;function myFunction(x, y) {(x == undefined && y == undefined) ? (x = 2, y = 12) : (x == undefined) ? (x = 12) : (y == undefined) ? (y = 2) : (x = x, y = y); return x * y;}//document.getElementById("demo").innerHTML = myFunction();console.log(myFunction());Multiple times, I wanted to post here for an answer, but I knew if it turn out to be simple, I would feel less. So for two hours or three, or maybe two and a half I spent trying to figure this out.How to concatenate multiple ternaries together. The problem was how I was arranging the condition of the conat-ternaries.I deserve a like... a point. Please someone give me a point for this simple, non-meaningful(concept in learning) trail....It doesn't matter if I figure it out by myself, the fact of how long it took me to get it right is defeat enough to make me feel less. -
cars = ["BMW", "Volvo", "Saab", "Ford"];var i = 2;var len = cars.length;var text = ""; // <~~~ Why the empty string again?for (; i < len; i++) { text += cars[i] + "<br>";} var text = ""; // <~~~ var i = 0; while (i < 10) { text += "<br>The number is " + i; i++;} -
ThanksWhen something is deprecated it is a notice to programmers that it is scheduled to be removed from a future version, and you should stop using it or change code that already uses it. The MDN reference explains why using the with statement can cause problems.https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/withhttp://en.wikipedia.org/wiki/Deprecate
-
So why would Mozilla declare it as so? Or better yet, why would one not use it?You're able to use it in any environment that uses Javascript. Whether or not it's a good idea is another thing.
-
... So I can use it in Node.js for serve scripting, but not in the browser for inline scripting, or external sheet scripting?Because it still is part of the language.
-
if the with statement is decrepit, why is it in EMCA-Script documentation?
-
Is English your native language? You seem to have trouble understanding what things are saying.
/* Using test */var a = str.test(exp);alert(a); // Shows "true" or "false"/* Equivalent operation: */var a = true;var e = str.exec(exp);if(e === null) { a = false;}alert(a); // Shows "true" or "false", the same value as it would in the previous example/* Using test */var str = "js";var exp = /"js"/var a = exp.test(str); alert(a); // Shows "true" or "false"/* Equivalent operation: */var a = true;var e = exp.exec(str);if(e === null) { a = false;}alert(a); // Shows "true" or "false", the same value as it would in the previous exampleYes... cause of my (refer to signature which will refer you to pic)... -
Is there away to set @keyframe animation with JavaScript? I tried it, but can't seem to get it to work.
-
Maybe I don't understand it in that content... You calling test is the same as FIRST calling exec(); calling them both? You're saying while calling them both, exec() first? That what it look like.What they're saying is correct. Calling test() is the same as first calling exec() and then returning true if the exec() return value isn't null.
-
Calling test() is equivalent to calling exec() and returning true if the return value of exec() is not null. Because of this equivalence, the test() method behaves the same way as the exec() method when invoked for a global regular expression: it begins searching the specified string at the position specified by lastIndex, and if it finds a match, it sets lastIndex to the position of the character immediately following the match. Thus, you can loop through a string using the test() method just as you can with the exec() method.No it's not! exec(); return an array of items, or null. test(); return a Boolean value!!!!!!! MMMMMMMMMMAAAAAAAAAAAAAWWWWWW!!!!!!!!
