    Enabling Javascript: Why Javascript Should be Enabled in the browser?

    Javascript makes the pages more dynamic and interactive at the same time exposing the user to many threats. In today's world, there is hardly any website that runs without javascript. If the javascript of the browser is disabled, most of the websites either don't show the data properly or ask the surfer to enable the javascript of his browser. So if a user wants to have a good experience surfing a website, he has to enable javascript. With the arrival of so many browsers, it is not easy for the surfer to locate the settings and enable the javascript of the browser. This article is focused on enabling the javascript of major browsers and their various versions.

    An Important Note Before Proceeding:

    In this article all the browsers are mentioned with their version numbers and their build numbers. The version number is followed by a period or a fullstop(.) which is then followed by the build number. There are subtle changes in various builds of the browsers but major revisions are made when the version is changed. If a browser (or any software or application fo that matter) is referred to as 1.x it can be a browser of version 1.0 or 1.1 or 1.2 or so on till 1.9.
