It has always baffled me why we are unable to write ES6 Maps in the following way:
new Map({
['ArrayAsKey']: {foo:bar}
})
Is there a workaround for this limitation? Or perhaps a technique that enhances the experience of utilizing these modern data structures.
I've always questioned why we are unable to write ES6 Maps in this way:
new Map({ ['ArrayAsKey']: {foo:bar} })
This method restricts keys to being strings only, as all other types will be coerced into strings.
However, it is possible to provide a list of key-value pairs instead:
const a = {foo: 13};
const b = {foo: 13};
const map = new Map([
[a, "const a"],
[b, "const b"]
]);
console.log(map.get(a), a);
console.log(map.get(b), b);Today marks my first venture into using Express. I attempted to create a straightforward route, but unfortunately, my save function is not cooperating. Despite scouring similar inquiries on stackoverflow, I have been unable to find a solution. Any assistan ...
