What is the technique for creating a mapping of an array containing various objects and values?

edit

The technique for creating a mapping of an array containing various objects and values is called "Array.map()". The map method loops through each element of the array and calls a provided function on each element. The function should take in the current element and return a new value, which is then added to the new array that will be returned by the map method. This allows the original array to be transformed into a new array with the desired object and value pairs.
