Which Version of jQuery File has to be used?

What makes jQuery so influential and universal?

The JavaScript language was origin in 1995. Since then, it’s functioning in different browsers (Google Chrome, Safari, Firefox) on the marketplace has made a pretty messy way. Over a lot of versions (both language browsers), some functions have been retained; another does not. Therefore, a single instruction can be known JavaScript in a browser and not in another, even in some form of a browser and not in another. What a bother for programmers!

Luckily, jQuery comes to the save: Defining its own set of orders, it works as a wrapper for diverse versions of JavaScript, whether existing or coming. On the other side, it lets browsers present on the marketplace, their several versions, and their compatibility with the rules of JavaScript and AJAX.

For a script written in JavaScript to run accurately on different forms of each browser, Programmer-like, you have to set up a series of tests and run a particular code for every browser and version.

With jQuery, these tests are needless: just run the essential instructions, in spite of the browser used, or version of JavaScript well-matched with this browser.

Where appropriate, the whole these tests are made so clear. In your situation, you only have to be anxious about the code.

Keep in mind, jQuery is very handy, but do not enjoy and consider only of the visual development: a page must leading base on solid HTML bases!
