javascript - Get variable from a string

Question

Does anyone know how could I select a variable from a String in JavaScript? Here's what I'm basically trying to achieve:

var myLang = "ESP";

var myText_ESP = "Hola a todos!";
var myText_ENG = "Hello everybody!";

console.log(myText_ + myLang); // This should trace "Hola a todos!"

Thanks!

Answer 1

var hellos = {
    ESP: 'Hola a todos!',
    ENG: 'Hello everybody!'
};

var myLang = 'ESP';

console.log(hellos[myLang]);

I don't like putting everything in global scope, and then string accessing window properties; so here is another way to do it.
