html - What client-side web scripting languages are there other than JavaScript and VBScript?

Question

1. How many client-side scripting language implementations did you see except JavaScript and VBScript? Like: type="text/C++Script", text/CSharpScript, text/oberonScript, etc.

2. How can I learn if my browser supports those languages?

Answer 1

The only languages I have ever seen supported by web browsers in <script> elements are:

• JavaScript / JScript (which is ubiquitous)
• VBScript (IE 10 and lower only)
• PerlScript (IE with a plugin from ActiveState only)
• Dart (in a nonstandard build of Chromium) which is not intended for production use.

The HTML 4 specification gives examples of Tcl, but I've never heard of a browser that implemented this.

In any practical sense (for WWW development), JavaScript is the only (not really a) choice.

There are also various languages (e.g. Dart, TypeScript, ES6/7) which have translators to convert programs to (ES5 flavoured) JavaScript which can then run in browsers.
