Big-O awareness for common operations
Understanding how long and how much memory basic JS operations usually take so you can write faster code.
"I want my app to stay fast as the data grows, not grind to a crawl."
Big-O describes how an operation's time or space grows as input size increases; for everyday JS tasks it sets realistic performance expectations so you pick the right data structure or algorithm.
