Create a deferred promise
Don't use this unless you know what you're doing! Prefer the Promise
constructor.
$ npm install --save p-defer
const pDefer = require('p-defer');
function delay(ms) {
const deferred = pDefer();
setTimeout(deferred.resolve, ms, '🦄');
return deferred.promise;
}
delay(100).then(console.log);
//=> '🦄'
The above is just an example. Use delay
if you need to delay a promise.
Returns an Object
with a promise
property and functions to resolve()
and reject()
.
