This file is the canonical resource for compatibility goals for the libraries that make up Sinon.JS.
The source is as ES2017 and requires no transpiler or polyfills in supporting runtimes.
For legacy runtimes, a transpiler can be used by dependent projects.
Sinon.JS aims at supporting the following runtimes:
> 0.5%
last 2 versions
Firefox ESR
not dead
not IE 11
not op_mini all
maintained node versions
The compatibility is enforced using eslint-plugin-compat.
To see what that means in practice, you can use https://browserslist.dev
