What’s is the benefit / drawback of these two alternatives?
Using object spread
options = ...optionsDefault, ...options;
Or using Object.assign
options = Object.assign(, optionsDefault, options);
Code Sample (doubles as compatibility test)
var x = a: 1, b: 2 ;
var y = c: 3, d: 4, a: 5 ;
var z = ...x, ...y;
console.log(z); // a: 5, b: 2, c: 3, d: 4
