Given an iterable over [key,value] pairs, Object.fromEntries() creates an object. It does the opposite of Object.entries. See the proposal1 for more information. Syntax console.log( Object.fromEntries([ ["foo", 1], ["bar", 2], ]) ); // { foo: 1, bar: 2 } Footnotes Footnotes https://github.com/tc39/proposal-object-from-entries ↩
