Javascript Logical Assignment Operators

Javascript Update

Javascript logical assignment operators include 3 operators :

Logical OR assignment operator : This will perform an assignment only when left hand side is a falsy value (false, 0, null, undefined, "").
```
// set x to y when x is falsy
x ||= y;
```
Logical AND assignment operator : This will perform an assignment only when left hand side is not a falsy value.
```
// set x to y when x is not falsy
x &&= y;
```
Logical Nullish assignment operator : This will perform an assignment only when left hand side is a nullish value (null, undefined)
```
// set x to y when x is nullish
x ??= y;
```
