Hello everyone,
please help the newbie figure it out.
There is such a JS code.
function makeDouble (x) {
return x * 2; }
var doMath = (x, func) => func(x + 5);
var num = 5;
The task is this: Using only makeDouble, doMath, and num, make the value of num equal to 20.
num = _____________________________________________________
I can’t understand why there are two parameters in the arrow function, but in the body of this function itself there is only one parameter. What am I doing wrong?
