Lastly, disabling JavaScript will take up less CPU and RAM on your computer, which is to be expected. We don’t encourage blocking ads, but if you must, there are better ways to do so than disabling JavaScript altogether. Most websites use JavaScript-it’s what makes the web we have today possible.ĭisabling JavaScript also prevents some types of ads from loading. However, this is extremely uncommon and the rare security holes in JavaScript engines have been patched very quickly. There have been a few browser vulnerabilities that were exploited via JavaScript. Many of these people do so because of a perceived security benefit. There is a small but vocal subset of users that disable JavaScript. Why Do People Want to Disable JavaScript? JavaScript isn’t the big security threat that Java was. It’s not an insecure plug-in produced by a single company, like Java is. JavaScript is built into your web browser-Chrome, Firefox, Internet Explorer, Safari, and Opera all have their own JavaScript engines. JavaScript and Java aren’t really related at all, aside from the name (which was chosen for marketing reasons). Note that JavaScript isn’t the same thing as Java. Most websites use JavaScript to provide various features. It’s the language that powers modern web apps, allowing web pages to dynamically load and send content in the background without page loads and do other dynamic, interactive things.
However, JavaScript has become much more than that.
JavaScript was initially pretty basic, and was used for things like alert boxes and menus that appeared when you hovered your mouse over elements on the page. JavaScript is a programming language commonly used on web pages (among other things).
