# arkcompiler_jsvm

#### Description
OpenHarmony JSVM-API provides a set of stable APIs based on the standard JavaScript (JS) engine. It provides complete JS engine capabilities, including creating and destroying a JS engine, executing JS code, and implementing interaction between JS and C/C++ modules.

OpenHarmony JSVM-API provides a set of APIs written in C programming language that complies with C99.

JSVM-API allows dynamically loaded JS code segment to be directly run during application runtime. With JSVM-API, you can also use C/C++ to implement core functionalities that demand high performance or closely rely on underlying system invocation, register C++ methods in JS code, and directly call the JS code to improve the execution speed.
