How to get an array of objects from a normal array in javascript

Question

I am trying to find a way to get an array of objects from a normal array without using a for loop.

An example for that I want to turn that array: [1,2,3,4,5]

To be an array of objects like that: [{x:1, y:2}, {x:2, y:4}, {x:3, y:6}, {x:4, y:8}, {x:5, y:10}] without using a for loop

• Rory McCrossan: What effort have you made? This seems to be a 'do my homework for me' question. Remember that SO is here to help you to debug code that you have written. It is not here to write code for you.
• Chris G: Kinda makes no sense as well, in the example you gave us you only have [1,2,3,4,5] but you want to "transform" that into an array of objects that have other elements that are not present in your initial array like 6,8,10 so what kind of rule are you even following to create your array?

Answer 1

You could map the array to a new array of objects:

result = [1,2,3,4,5].map(i => ({x: i, y: i*2}));
