if a value is an async function, from ES2017 specification\n\nSupports runtime implementations, as well as babel transpiled code.\n\n```js\nconst isAsyncFunction =

is-async-func\n```\n\n## Should I use this?\n\nFor runtimes that support async/await, yes!\n\nFor transpiled async/await, probably! :grimacing:  \nThe transpilation tests cover many different combinations of async declarations and babel transform presets, but the transpiled detection generally takes a hacky approach. Probably-definitely don't use this in hot code.\n\n## License\n\nLicensed under the MIT License, Copyright © 2017 Lochlan Bunn.","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Floklaan%2Fis-async-func","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Floklaan%2Fis-async-func","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Floklaan%2Fis-async-func/lists"}
