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_

You can use eval for that but this is very bad practice:

console.log(eval("myText_" + myLang);

I'll suggest to have an object instead:

var myLang = "ESP";
var texts = {
    'ESP': "Hola a todos!",
    'ENG': "Hello everyboy!"
};
console.log( texts[ myLang ] );
