How to find linear regression?

Question

JavaScript

I have an array of objects like

const arr = [
{x: 20.849203669054898, y: 20.849203669054898}
{x: 31.784082508100216, y: 31.784082508100216}
{x: 45.66296718842696, y: 45.66296718842696}
{x: 45.99942499885912, y: 45.99942499885912}
{x: 48.01817186145211, y: 48.01817186145211}
{x: 59.205394058321545, y: 59.205394058321545}
{x: 62.065285446994935, y: 62.065285446994935}
{x: 82.50509743074888, y: 82.50509743074888}
{x: 83.76681421986947, y: 83.76681421986947}
{x: 85.36498881942225, y: 85.36498881942225}
{x: 86.54259115593483, y: 86.54259115593483}
]

These are the coordinates of the points. How to find a linear regression based on this data?
The output needs data of the same type as the original array, that is, with x and y.
