If an object is created from pairs, and only used to check existence and READ properties. Should prefer use new Map() instead of Object.fromEntries(), kind of similar to prefer-set-has.
Fail
const object = Object.fromEntries(/*...*/);
if (object.foo) {
console.log(object.foo)
}Pass
const object = new Map(/*...*/);
if (object.has('foo')) {
console.log(object.get('foo'))
}// Object literal should be ignored
const object = {
// ...
};
if (object.foo) {
console.log(object.foo)
}
