JavaScript Loops are easy, learn in 5 minutes (2026)
Mastering JavaScript Loops and Conditioning is the secret to moving from a beginner to a pro developer! In this video, I walk through my personal handwritten notes to explain how to control your code's flow.
Of course, it was converted into video representation.
Are you confused about when to use a For Loop vs a While Loop? Or why a Do-While Loop always runs at least once even if the condition is wrong? I’m breaking down the logic of decision-making in JavaScript using my handwritten notes.
🚀 What You Will Learn:
Boolean Negation: Understanding the !flag logic in if/else statements.
While Loops: Setting conditions and preventing the "Infinite Loop" with the break keyword.
Do-While Logic: Why the iteration runs once before checking the condition, even if it's invalid.
For Loops: When to use them (specifically when you know your iteration count in advance!).
Advanced Coding Logic: Finding the first 3 numbers divisible by 2 AND 5 using a loop, iteration counting, and a break.
💡 Key take-away: Use a For Loop when you know the number of repetitions in advance; use a While Loop when the count is unknown and based on a condition.
