Показать описание
In this video, we solve the DSA problem: "Count the Number of Positive, Negative, and Zero Elements in an Array" using JavaScript. This is a great exercise to practice conditional logic and basic iteration techniques.

What you’ll learn:

Looping through arrays and using conditional statements

Counting multiple categories in a single pass

Clean JavaScript logic to track positives, negatives, and zeros

Handling edge cases: all positive, all zero, all negative, empty array

Time and space complexity breakdown

An excellent problem to reinforce control flow, counters, and array traversal — perfect for coding interview warm-ups.
