Lets see how you know javascript!
--
Write a function that takes an argument and returns that argument

idf = identify(3);
idf() //3

My attempt

function identify(q){
return q;
}

idf = identify(2);

idf() //"TypeError: 2(value of expression idf) is not object"

This should be pretty easy to implement.

function identify(val){
         this.val = val;
         return val;
}
identify(3)                          --> 3
identify("Tunde" )                --> "Tunde"
identify({name: "Osewa"})   -->  Object {name: "Osewa"}

you are wrong you didn't follow the rule, where is the idf variable?

function identify(q){
return function(){
return q;
}
}

idf = identify(3);
idf() //3

Oh, I'm supposed to set a variable equal to the result of calling the identify function. Why do I need to call it like a function?

Try this:

function identify(){return arguments[0];}
alert(identify(3));

Try zat
