change property name

Question

I have a JavaScript object as follows:

var a = { Prop1: \'test\', Prop2: \'test2\' }

How would I change the \"property name\" of Prop1 to P

Answer 1

Using the proposed property rest notation, write

const {Prop1, ...otherProps} = a;

const newObj = {Prop3: Prop1, ...otherProps};

This is supported by Babel's object rest spread transform.
