Looks confusing at first, but I found it nice for accessing a month array.

const months = ["Jan", "Feb", ...];

months[0] === "Jan";

const label = months[date.getMonth()];

You bought it for something where it was the only option, driving 30km to work everyday. But ever since you got it, the trip to the super market is kinda too hot in the summer and too cold in the winter and what if you spontaneously need to buy more than expected?

People learn it for front end dev, and then they use what they know for back end too.

And typescript is basically just a linter on steroids
