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

I smell a bad practice. What problem are you trying to solve by doing this? — Jonathan M

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]();
}
