In my learning of 'Control Flow' in JavaScript I ran into the Ternary Operator (or Condtional Operator). I find these to be just to cool not to write a little about them.
The Ternary Operator is a real short way to choose between two things instead of using if/else. They a basically structured as:
condition ? if true : if false; The ? is your operator.
So lets do an example.
if (cheese === 'Yellow') {
console.log("Got me some yellow cheese!");
} else {
console.log("Got me some moldy cheese!");
}
So doing the above if/else the "Ternary way" would look more like this.
cheese === "Yellow" ? console.log("Got me some yellow cheese!") : console.log("Got me some moldy cheese!");
- So we have our condition -
cheese === "Yellow" - Our True -
console.log("Got me some yellow cheese!") - And our False =
console.log("Got me some moldy cheese!")
I don't know why I love this so much. Well I do, it just makes things a bit simpler in my eyes. So give them a go if you haven't before. They are pretty fun.
Cheers!

There's nothing more beautiful than a well executed ternary expression.
It becomes especially useful when working with templates where you want a simple inline way of switching between behaviors or components.
If you'd like some more things to look into, thing about what happens when you use logical operators (
&&,||) to determine what parts of code run (also super useful when templating, but also for providing defaults likeconst x = someParameter || 'defaultString').I would do something like this…
Why? : Think about if you not just
console.logor do async functionsThat's very cool, I'm still learning my way around myself so i'm pretty positive I haven't come close to wrapping my mind around all the possibilities.
