JScript is Microsoft's legacy dialect of the ECMAScript standard that is used in Internet Explorer and HTML Applications, and as a standalone Windows scripting language.[1]
History[]
First supported in Internet Explorer 3 in August 1996, its most recent version is JScript 9.0, included with Internet Explorer 9. Microsoft transitioned to the Chakra open-source JScript and JavaScript engines for improved performance in the latter versions of Explorer to early versions of Microsoft Edge (now called Edge Legacy). In 2018, Edge switched to the V8 JavaScript engine from Google's Chromium browser platform.[2]
JScript 10.0[3] is a separate dialect, also known as JScript .NET, which adds several new features from the abandoned fourth edition of the ECMAScript standard. It must be compiled for .NET Framework versions 2 or 4, but static type annotations are optional.[citation needed]
JScript was criticized for being insecure and having multiple security bugs "exploited by nation-state actors",[4] leading Microsoft to add an option to disable it.[5]
