List of ECMAScript engines
- Chakra: A JScript engine used in Internet Explorer. It was first previewed at MIX 10 as part of the Internet Explorer 9 Platform Preview.
- Tamarin: An ActionScript and ECMAScript engine used in Adobe Flash.
The following engines use runtime interpreters, which do not compile into native machine code and generally run more slowly.
- Continuum: A self-interpreter that supports recent iterations of the draft ECMAScript 6 specification. Uniquely, the engine is implemented in ECMAScript 3, which makes it possible to run ES6 in browsers as old as IE6.
- Futhark: The ECMAScript engine of the Opera web browser versions 9.50 to 10.10.
- InScript: An obsolete proprietary library used for iCab 2 and 3
- JScript: The engine that is used in Internet Explorer for versions up to IE9, and one component of the Trident layout engine.
- Linear B: The ECMAScript engine of the Opera web browser versions 7.0 to 9.50, exclusive.
- YAJI: An ECMAScript engine based on the FESI implementation by Jean-Marc Lugrin in 1999, using the Java platform, currently being developed to support the latest standards (Spec 262, v5.1).
- Duktape: a small footprint, easily embeddable Ecmascript E5/E5.1 engine.
