Great video. I am always looking for videos on how to solve algorithms. How about some problems from codewars or leetcode? thanks

question, how would you use the spread operator to merge a list of two objects, based on their id, i.e. we have list1 = [{id: 1, name: 'enrique'}, {id: 2, name: 'jason'}], and list2 = [{id: 1, age: 25'}, {id: 2, age: 26}], the desired result being finalList = [{[{id: 1, name: 'enrique', age: 25}, {id: 2, name: 'jason', age: 26}]

If after combining array 1 and array 2, you codify array 1 will this modified the array combined ???
Hoy can i add and array to the existing one, not create another one but adding them to the existing one ???
