I'm switching between JavaScript and TypeScript
I'm switching between JavaScript and TypeScript. I've noticed TypeScript has a lower mental load.
Here's why:
In JS I have to remember object shapes and call signatures.
In TS I declare my types once. Then I lean on them. So TS frees up my short-term memory. 👍
#typescript
Another example where TS reduces mental load:
In JS, when I make a breaking API change, I have to remember all the spots I need to update.
In TS, no short-term memory or manual searching is required. I just lean on the compiler.
Oh, and if you want to learn TypeScript, here are three resources I found helpful:
