JawaScript is a minimized subset of JavaScript. It consists of a Java-based parser and an Android executive engine. (iOS executive is under development.) Its goal is to provide a dynamic scripting environment for mobile APPs with a minimal size overhead. Currently, the size of the Android executive is less than 20K.

The executive engine is a LOW-performance interpreter executing the AST generated by the parser. So, don't use it in time-critical routines.

An adequate description for the syntax of JawaScript is "type-less C." For the size constraint many JavaScript features are excluded from JawaScript:

• No literal template

• No unicode support in identifier

• No complex identifier

• No spread operator

• No regular expression

• No octal string

• 0x2028 and 0x2029 are treated indifferently from ordinary characters

• No unicode character in string literal

• Support only {x, u, r, n, t, v} in string escaping

• No exception handling (try, catch, throw, finally)

• No yield nor generator

• No class, super, extends

• No const

• No export, import

• No debugger

• No comment

• No switch

• No this

• No eval

• No directive prologues

• No unnamed functions

• No ... in parameters

• No default value in parameters

• No nested function declaration

• No labeled statement

• No anonymous function

• No arrow function

• No new.target
