    Non-standard
    This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

    Summary

    The isGenerator() method determines whether or not a function is a generator.

    fun.isGenerator()

    Description

    function g () {
      yield 42;
    }
    
    console.log("f.isGenerator() = " + f.isGenerator()); // f.isGenerator() = false
    console.log("g.isGenerator() = " + g.isGenerator()); // g.isGenerator() = true
