Lodash的'omit（）'的纯JavaScript替代

function omit(obj,attr) {
const { [attr]: _,...newObj } = obj;
return newObj;
}
console.log(omit({ foo: 'foo',bar: 'bar',baz: 'baz' },'bar'));

function omit(obj,...keys) {
const keysToRemove = new Set(keys.flat()); // flatten the props,and convert to a Set
return Object.fromEntries( // convert the entries back to object
Object.entries(obj) // convert the object to entries
.filter(([k]) => !keysToRemove.has(k)) // remove entries with keys that exist in the Set
);
}
console.log(omit({ foo: 'foo','bar'));
console.log(omit({ foo: 'foo','bar','baz'));
console.log(omit({ foo: 'foo',['bar','baz']));
console.log(omit({ foo: 'foo',['baz']));
