listToMap.js

const iconList = [
  { name: 'star',  code: 7807, size: 20 /* ... */ },
  { name: 'heart', code: 7897, size: 10 /* ... */ },
  { name: 'arrow', code: 7822, size: 25 /* ... */ },
  { name: 'home',  code: 7901, size: 20 /* ... */ }

const entries = iconList.map(({ name, ...rest }) => [ name, rest ])

const icons = new Map(entries)

console.log([...icons.keys()])
// -> ["star", "heart", "arrow", "home"]
console.log(icons.get('star'))
// -> { code: 7807, size: 20, ... }
