JavaScript shorthand version to invert boolean?

Usually, you invert a bool because you are going to be using it somewhere with its inverted state. Rather than inverting the bool and assigning it back to itself, just use the inverted version elsewhere. So instead of this:

myBool = !myBool;
someFunction(myBool);

Do this:

someFunction(!myBool);

Of course, that doesn't make sense if you have something like this:

if(someCondition) {
    myBool = !myBool;
}
// Lots of code that uses myBool.

In that case, just suck it up and type the massive amount of code required to invert the bool. :rolleyes:

if you create your own constructor that lets you access a boolean then you can flip it with only one reference:

function Bit(bit=false) {
  this._ = bit;
}
Bit.prototype.flip = function() {
  this._ = !this._;
  return this._
}

//example:
var foo = new Bit();
console.log(foo._) //logs false
foo.flip() //flips to true
console.log(foo._); //logs true
console.log(foo.flip()) //flips to false and logs it

this._ = !this._
