描述
Bad
function doStuff(input) {
if (input === "stuff") {
return Promise.resolve(true);
}
return false;
}
Consider the following:
doStuff("stuff")
.then(result => console.log(result)); // => true
doStuff("other") // *****Cannot call .then on false!*******
.then(result => console.log(result));
It should always return a Promise!
Good
function doStuff(input) {
if (input === "doIt") {
return Promise.resolve(true);
}
return Promise.resolve(false);
}
