Key characteristics of JerryScript:

* Full ECMAScript 5.1 standard compliance

* ECMAScript 2025 standard compliance is 70%

  * [Kangax Compatibilty Table](https://compat-table.github.io/compat-table/es2016plus/)

* 258K binary size when compiled for ARM Thumb-2

* Heavily optimized for low memory consumption

* Written in C99 for maximum portability

* Snapshot support for precompiling JavaScript source code to byte code

* Mature C API, easy to embed in applications
