Dev.to

When I started coding, certain buzzwords would immediately make me feel like I was miles away from being a "real developer." Turns out... most of them were way less scary than I thought. Here’s my list of things that sounded super advanced but turned out to be surprisingly simple (and fun!): 1. Debouncing and Throttling What I Thought: "Omg, this must involve hardcore math and wizard-level timing." Reality: Debouncing = Wait until the user stops typing/clicking before you react. Throttling = Limit how often something happens. Example in plain English: "Don't call the API every keystroke. Wait for 500ms of no typing. Then call." That's it. ✨ 2. useMemo and useCallback in React What I Thought: "Only senior engineers understand hooks like these." Reality: They just remember things (so React doesn’t redo heavy calculations or recreate functions unnecessarily).

When I started coding, certain buzzwords would immediately make me feel like I was miles away from being a "real developer."
Turns out... most of them were way less scary than I thought.

Here’s my list of things that sounded super advanced but turned out to be surprisingly simple (and fun!):

1. Debouncing and Throttling

What I Thought:
"Omg, this must involve hardcore math and wizard-level timing."

Reality:
Debouncing = Wait until the user stops typing/clicking before you react.
Throttling = Limit how often something happens.

Example in plain English:

"Don't call the API every keystroke. Wait for 500ms of no typing. Then call."

That's it. ✨

2. useMemo and useCallback in React

What I Thought:
"Only senior engineers understand hooks like these."

Reality:
They just remember things (so React doesn’t redo heavy calculations or recreate functions unnecessarily).
