Now Google uses new techniques to speed up Javascript load times in latest Chrome release

People are always obsessed with speed, Google  has improved the way Chrome loads Javascript files in the latest version of Chrome, now loading at the same time as beginning to parse them.

Script streaming in Chrome 41 allows the browser to process asynchronous and deferred scripts

as soon as the download of those files begins, not after it’s completed. Previously, the browser

would download and then parse the files step by step.

This improvement means that pages can load up to 10 percent faster than previously.have a look at this

Code caching is also used in Chrome 42 to help speed up sites you frequently visit. Google says

that traditionally, the browser compiles a page’s Javascript on every visit, but the new build of

Chrome stores a local copy of compiled code for execution on frequently visited sites.

Google touts this technique as saving up to 40 percent of compile time and reducing battery drain

on mobile devices, which is great news for everybody.
