Description
Creates a new JavaScript engine instance.This object contains all the functions and properties you defined.
Please release the object later with the JS.Release function.
Your own JavaScript engine is useful for:
- Running some snippet of JavaScript code without web viewer.
- Using various JavaScript libraries
- Providing a scripting language to your own solution.
- Doing JavaScript on server side.
- Working with JSON data
- Enjoy using regular expressions, unicode text functions, number parsing and formatting with no platform dependencies
If JSRef is "js", we use this one as the global JavaScript engine for custom functions and JS.CF function. See our example JavaScript Custom Functions.
When using a name for the reference number, you can use this reference anywhere you need to pass a JavaScript reference number.
Check also our JavaScriptWebKit functions for using WebKit’s JavaScript engine on macOS and iOS.
