E0036: stray comma in let statement

Variables declared by const, let, and var must be separated by a comma (,). It is a syntax error to have multiple commas separating variables:

let p = findCenterPoint();
let x = p.x,;
let y = p.y - 1;

To fix this error, remove the extra comma:

let p = findCenterPoint();
let x = p.x;
let y = p.y - 1;
