Javascript object clone
var obj = {a: 1 ,b: 2}
var objclone = Object.assign({},obj);Now the value of objclone is {a: 1 ,b: 2} but points to a different object than obj.
Note the potential pitfall, though: Object.assign() will just do a shallow copy, not a deep copy. This means that nested objects aren’t copied. They still refer to the same nested objects as the original:
let obj = {
a: 1,
b: 2,
c: {
age: 30
}
};
var objclone = Object.assign({},obj);
console.log('objclone: ', objclone);
obj.c.age = 45;
console.log('After Change - obj: ', obj); // 45 - This also changes
console.log('After Change - objclone: ', objclone); // 45

You were not mistaken
I apologise, but it not absolutely approaches me. Perhaps there are still variants?
