import type { ObjMap } from './ObjMap';
/**
* Creates a keyed JS object from an array, given a function to produce the keys
* for each value in the array.
*
* This provides a convenient lookup for the array items if the key function
* produces unique results.
* ```ts
* const phoneBook = [
* { name: 'Jon', num: '555-1234' },
* { name: 'Jenny', num: '867-5309' }
* ]
*
* const entriesByName = keyMap(
* phoneBook,
* entry => entry.name
* )
*
* // {
* // Jon: { name: 'Jon', num: '555-1234' },
* // Jenny: { name: 'Jenny', num: '867-5309' }
* // }
*
* const jennyEntry = entriesByName['Jenny']
*
* // { name: 'Jenny', num: '857-6309' }
* ```
