If you use it, and call the function with no parameters, it works:
function drawES6Chart({size="big", cords = { x: 0, y: 0 }, radius = 25} = {}) {
console.log(size, cords, radius);
// do some chart drawing
}
drawES6Chart();
if not, an error is thrown:
TypeError: can’t convert undefined to object
function drawES6Chart({size="big", cords = { x: 0, y: 0 }, radius = 25}) {
console.log(size, cords, radius);
// do some chart drawing
}
drawES6Chart();
