Use Intl.NumberFormat to enable country / currency sensitive formatting.
The Exponent Operator
Do you useMath.pow() to raise a number to a power? Did you know you can use the exponent operator ** as well?
Calculate the midpoint between two pairs of (x,y) points
Destructure the array to get x1, y1, x2 and y2. Calculate the midpoint for each dimension by dividing the sum of the two endpoints by 2.
