object creation syntax

[jimfog]

Recently, in a tutorial I came across with this syntax:

var prop, obj = { name: "Joe", job: "Coder", age: 25 };  

I really cannot understand what the prop is doing there.

 

It is like assigning the object to 2 variables, furthermore in the w3schools tutorials about object creation

I saw nowhere similar syntax.

 

So, what the above means?

Unless the writer of the code is making a mistake.

A single var keyword can initialize an arbitrary number of variables as long as they are separated by a comma. At the same time, you can set an initial value for any of them. In this case, only the second variable is being initialized to a value.

similar syntax to

 

var prop;var obj = { name :"Joe", jon: "Coder", age: 25 };
