Ternary Operator - Javascript In Depth

We take a look at the ternary operator in Javascript together. This allows us to shorten certain types of conditional statements down to a single expression. There are several caveats to using this syntax which we explore.

We also look at how this helps us with the newer arrow function expression syntax as well as within high-order array functions like map.

i'm prepping for my software development bootcamp this playlist will come in handy

this was very important, the short arrow function syntax. earlier i use to get confuse when i read other people's code. and i was like, what the hell is this. now i got it.

I’m kinda not the biggest fan of the “most efficient” syntax here. I appreciate what it does but it just seems a bit too nuanced in its application - not sure how much I’ll actually use it over maybe the less optimized ternary expression or even a good old if/else statement 🤷🏻‍♂️
