Object.fromEntries

Today I learned about Object.fromEntries() in javascript which essentially lets you convert a list of key/value pairs into an object (this is the same as the lodash function fromPairs).

This came in handy when I needed to convert a list of entities into a lookup object like:

Object.fromEntries(
  users.map((user) => {
    return [user.id, user.isSelected];
  })
); // => { '1': true, '2': false, '3': false }
