Why is my variable undefined inside the Underscore.js each function?

Question

Here is my code:

TextClass = function () {
    this._textArr = {};
};

TextClass.prototype = {
    SetTexts: function (texts) {
        for (var i = 0; i < te

You have to pass this as context for _.each call like this:

_.each(texts, function (text) {
    this._textArr[text.Key] = text.Value;
}, this);

See the docs for http://underscorejs.org/#each
