In JavaScript, I can delete an object's key with

delete myObject[myKey];

Is there an efficient way to delete multiple keys using one line? Something that looks like:

multiDelete myObject[keyOne, keyTwo, keyThree];

Here's a one-liner similar to what you're requesting.

var obj = {a: 1, b: 2, c: 3, d: 4, e: 5 };



['c', 'e'].forEach(e => delete obj[e]);



// obj is now {a:1, b:2, d:4}
