How to declare a dynamic local variable in Javascript

Question

I want to create a local variable dynamically. JavaScript: Dynamically Creating Variables for Loops is not exactly what I am looking for. I dont want an array. I want to access

Answer 1

This answer is more or less the same as several answers above but here with a simplified sample, with and without using eval. First using eval (not recommended):

var varname = 'foo';  // pretend a user input that
var value = 42;
eval('var ' + varname + '=' + value);

And alternatively, without using eval:

var varname = prompt('Variable name:');
var value = 42;
this[varname] = value;

I hope this helps.
