Where is the function 'define' defined in this codebase?

I was looking through file upload plugin's javascript code.

There is a piece of code which checks if define is a function and declares a few dependencies i guess

(function (factory) {
    'use strict';
    if (typeof define === 'function' && define.amd) {
        // Register as an anonymous AMD module:
        define([
            'jquery',
            'jquery.ui.widget'
        ], factory);
    } else {
        // Browser globals:
        factory(window.jQuery);
    }
}

The comments just above the code says define is global. But i dont have it in my application built using angularjs.

I searched the codebase for declaration of define. BUt couldn't find any. I googled for AMD and i could see define being used here again.

My question is where is 'define' defined?

define is a function whose functionality is defined by the Asynchronous Module Definition spec­if­i­cat­ion. AMD is just a spec; there's multiple implementations, of which RequireJS is one. You could see how RequireJS implements it if you want, but keep in mind that RequireJS's define isn't the only define out there.
