IE still supports vbscript. I doubt it's used much anymore - maybe on some corporate intranet. Just a note from the future : it is not anymore, or at least it is now allowed to bring friends at home : developer. This should probably be reopened, because it meets the scope requirements of the community-defined topics: " software tools commonly used by programmers " and is " a practical, answerable problem that is unique to software development.

One particular comment summed it up nicely as to why there has been some resistance to that: In this case the feature is exposing additional programming languages to the web, something without any real benefit to anyone other than fans of the current "most awesome" language not too long ago that might have been Go, a year or so ago this would have been ruby, before than python, i recall i brief surge in haskell popularity not that long ago as well, Lua has been on the verges for a long time, in this case it's Dart -- who's to say there won't be a completely different language in vogue in 6 months?

We love javascript because the mayor browsers support it!!! I think that a better direction would be to split the javascript engine into two parts: A language compiler for each language, javascript, python, dart or whatever that turns code into ASM. This way there wouldn't be a significantly bigger burden on browsers and the choice of client-side languages would be bigger. Browser industry and consequently Javascript resemble oil industry! Both try hard to hide a better and safer world from people by selling them big lies.
We're all oil-addicted without knowing that there has been greener alternatives since decades ago. Same goes here, a poorly designed language is still the only reliably supported one by all major browsers. That's why humanity makes progress at such a slow rate. We're afraid of change! Wouldn't it make sense to build in VM for s.

Because JavaScript is what every other browser supported, and browser vendors had two main priorities: Making sure existing webpages worked which requires JavaScript Letting authors do user visible things in their browser that they couldn't do in other browsers changing programming language would be entirely hidden from users, except when it broke.
This is why developers prioritize efficiency in JavaScript functions and make the amount of data communicated between the programs as small as possible. Only once the user selects a search term does the entire page reload and produce the search results. Engines such as Google have reduced or eliminated the need to reload, even for that step. They simply produce results using the same asynchronous process.
While JavaScript is not the only client-side scripting language on the Internet, it was one of the first and it is still the most widely used. Many developers believe that JavaScript is inefficient and finicky, so they have made many improvements to the language over the years. Enterprising programmers have created JavaScript libraries - more concise languages constructed from the building blocks of JavaScript that are less complex and can be targeted for specific applications.
For instance, JQuery is a JavaScript library that simplifies and expands many of JavaScript's animation and interactive functions, while Backbone.
JavaScript has become integral to the Internet experience as developers build increased interaction and complexity into their applications. Search engines, ecommerce, content management systems, responsive design, social media and phone apps would not be possible without it. Start your free trial High-volume or established business?

Some of the dynamic website enhancements performed by JavaScript are: Autocomplete Loading new content or data onto the page without reloading the page Rollover effects and dropdown menus Animating page elements such as fading, resizing or relocating Playing audio and video Validating input from Web forms Repairing browser compatibility issues While JavaScript is a client-side language, some of its most powerful features involve asynchronous interaction with a remote server.

Adding interactive behavior to web pages JavaScript allows users to interact with web pages.
There are almost no limits to the things you can do with JavaScript on a web page — these are just a few examples: Show or hide more information with the click of a button Change the color of a button when the mouse hovers over it Slide through a carousel of images on the homepage Zooming in or zooming out on an image Displaying a timer or count-down on a website Playing audio and video in a web page Displaying animations Using a drop-down hamburger menu 2. Creating web and mobile apps Developers can use various JavaScript frameworks for developing and building web and mobile apps.
Building web servers and developing server applications Beyond websites and apps, developers can also use JavaScript to build simple web servers and develop the back-end infrastructure using Node. Game development Of course, you can also use JavaScript to create browser games. Why use JavaScript over other programming languages?
