Question

How can I create a function that requires input in JavaScript?

Example:

var a = 0;
var b;
function A(int myInteger){    //should it be something like var myInteger?
 // do something with myInteger
// print something or do a = myInteger;
}
function B(a){
// do something with recieved integer
}

Please help me.

There is no data types in JavaScript other than var everything is var in JS .

So when passing variable need not be mention the var also .just pass your value .same on creating function also .just mention the variable name. That’s it .

so

var a = 0;
var b;
function A(a){    //passing your varible 
 // do something with a
// print something or do a = myInteger;
}
function B(b){
//Ex :call function A here 
A(b);
} 

//Cheers .

As all said ..welcome to JS and W3School too.
