JavaScript Generators
Introduction#
Generator functions (defined by the function* keyword) run as coroutines, generating a series of values as they're requested through an iterator.
Syntax#
- function* name(parameters) { yield value; return value }
- generator = name(arguments)
- { value, done } = generator.next(value)
- { value, done } = generator.return(value)
- generator.throw(error)
Remarks#
Generator functions are a feature introduced as part of the ES 2015 specification and are not available in all browsers. They are also fully supported in Node.js as of v6.0. For a detailed browser compatibility list, see the MDN Documentation, and for Node, see the node.green website.
