util.types.isGeneratorObject(value)


如果值是从内置的生成器函数返回的生成器对象,则返回 true。 这只会报告 JavaScript 引擎看到的内容;特别是,如果使用了转译工具,则返回值可能与原始源代码不匹配。

function* foo() {}
const generator = foo();
util.types.isGeneratorObject(generator);  // 返回 true

Returns true if the value is a generator object as returned from a built-in generator function. This only reports back what the JavaScript engine is seeing; in particular, the return value may not match the original source code if a transpilation tool was used.

function* foo() {}
const generator = foo();
util.types.isGeneratorObject(generator);  // Returns true
