Way to iterate through object to create array of objects

Question

I have an object that I want to use the keys as keys in a new object and the value into a child object. How could I go from A to Z?

const a = {key1: 'text', key2: 'text2'}

const z = [{ key1: { similarTo: 'text' } }, {key2: {similarTo: 'test2'}}]

You can use Object.entries and Array.prototype.map in order to achieve it:

const a = {key1: 'text', key2: 'text2'};
const z = Object.entries(a).map(([k, v]) => ({ [k]: { similarTo: v } }));

console.log(z);

I like this, but find ... .map(([k, v]) => ({ [k]: { similarTo: v } })) easier to understand

Is there also a way I could add a switch statement in there to check what the key so that I could change the similarTo to something else?

@ScottSauyet - I agree and therefore edited my answer. Thank you.

@bananapancakes3 - You can switch inside the map clause if you really want to.
