The Object.assign() Method in JavaScript - Set default options for functions

Показать описание

The assign() method on the Object constructor in JavaScript is used to merge multiple objects together. You can use it to merge as many objects as you like.

If multiple objects have the same property, the "merged object" will also contain that property but the value of it will come from the last object passed in as an argument. This means it can be used to easily create "default options" within a function.

It should be noted that by the steps shown in the video, the original course object is edited as well to now include a score property.

If found out, that defaults is OVERWRITTEn.
So instead of:
options = Object.assign(objct1, objct2)
console.log(objct1)
//you can just write
Object.assign(objct1, options)
console.log(objct1)

Why would you (and everyone else) teach, that Object.assign passes something to options, while it seems, that actually Object.assign just overwrites the first object with the second object.

you can not use the first object more then once, since its overwritten with the assign method. nobody mentions this. its just "creating a new object", but ist not realy, righT?! :o
