How to connect function name with var javascript ?

i want to connect myFunction with var zz.

i try to like this but not work, how can i do that ?

<script>
for(var zz = 0; zz < 3; zz++)
{
    function myFunction'+var zz+'() {
         -------------SOME CODEING---------------
        } 
}
</script>

Define function outside of the loop, pass a param into its call (`myFunction(zz);`). — raina77ow, Dec 01 '14 at 17:07

I smell a bad practice. What problem are you trying to solve by doing this? — Jonathan M, Dec 01 '14 at 17:14
What exactly do you mean by "connect function name with var"? — Felix Kling, Dec 01 '14 at 17:20
@FelixKling, he wants functions named like `myFunc1`, `myFunc2`, `myFunc3`, etc. by looping a variable. — Jonathan M, Dec 01 '14 at 17:24

Perhaps a good way of doing this is to store your functions in an object and then reference those in your loop:

var obj = {
    fn0: function () {
        console.log(0);
    },
    fn1: function () {
        console.log(1);
    },
    fn2: function () {
        console.log(2);
    }
}

for (var zz = 0; zz < 3; zz++) {
  var fnName = 'fn' + zz;
  obj[fnName]();
}

Or perhaps even better:

for (var zz = 0, l = Object.keys(obj).length; zz < l; zz++) {
  var fnName = 'fn' + zz;
  obj[fnName]();
}
