Lets say I have a function like this:
function foo(){
return () => {
return "bar"
}
}
foo()() // => "bar"
Is there a way for this to return something other than a function without the use of a parameter?
foo()() // => "bar"
foo() // => "foo"
No. If the value returned must be callable later, then it has to be a function - no exceptions.
You could put a property on the function, though.
function foo(){
return Object.assign(
() => {
return "bar"
},
{ prop: 'bar' }
);
}
console.log(foo()());
console.log(foo().prop);Or return both a function and something else.
function foo(){
return [
() => {
return "bar"
},
'bar'
];
}
const [fn, val] = foo();
console.log(fn());
console.log(val);
