Javascript Question

Write name of array on the go from name + variable

I have such array component which prints out Good.


But now I want to print it out like this

var ccc='componentA';

But it's not working unfortunately :(
Where is my mistake ?


Although it's not recommended, you can do this in Javascript without having to use eval(). Since global variables are descendants of the window object, you can access them like this:

var ccc='componentA';
console.log(window['nameA_' + ccc]['abc'].aaa);

But it's probably better practice to use objects / arrays instead of using this method.
