Can I use a variable to name other variables?

Can you use variables in a variable name in Javascript?

• var array1 = new Array(4); var array2 = new Array(4); var array3 = new Array(4); var array4 = new Array(4); var array5 = new Array(4); var array6 = new Array(4); var array7 = new Array(4); for(var a = 1; a < 8; a++){ array+ a = new Array(4); } I want to make an array with a for loop, but the variables has to be diffrent every time. So my question if this is possible, and if it is, how?

• Answer:

  No you can't (not unless you use Eval() which you shouldn't...). As Justinas has commented, you could use a Multidimensional array. var array = []; array.push(new Array(4)); array.push(new Array(4)); array.push(new Array(4)); array.push(new Array(4)); array.push(new Array(4)); array.push(new Array(4)); array.push(new Array(4)); for(var a = 1; a < 8; a++){ array[a] = new Array(4); }
