/**

* 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
|
