-Sinon has historically been written as [ES5][es5], but starting from Sinon 10 (March 2021) we made the breaking change to allow more modern ECMAScript versions, starting with ECMAScript [2017][es2017]. This is not a fixed level: it will change in time without us updating it here. The source version requires no transpiler or polyfills in supporting runtimes.

-For legacy runtimes, a transpiler can be used by dependent projects., but use of newer APIs might break. If you need to support older browsers, have a look at Sinon 9.
