Which browsers support Microsoft JScript?

Question

Which browsers support Microsoft JScript?

Answer 1

Only IE (and IE-based browsers like Maxthon) and, if you consider the windows desktop sidebar a browser, the windows desktop sidebar which uses IE internally. So don't use it unless the latter is your target environment.

Other browsers support JavaScript though which is what's used for active content on websites nowadays.

Answer 2

JScript is the name that Microsoft has chosen for its implementation of ECMAScript, Document Object Model and related APIs. Microsoft does not call it JavaScript, because Oracle holds the copyright on that name. Everyone else calls it JavaScript.

Only Internet Explorer and browsers based on it's rendering engine support true JScript (i.e. including it's omissions from, deviations from and additions to the standards).
