Learn Lua in Neovim: Numeric For Loops — Count, Step & Countdown | Episode 9

Repeat code with for loops in Lua! In this episode we learn for i = start, stop do, add a step value to count by twos, count down with a negative step, build a multiplication table, and sum 1 to 100. Every keystroke is shown on screen with 3-second pauses so you can follow along at your own pace. What You'll Learn: - for i = 1, 5 do — basic counting loop - for i = 2, 10, 2 do — step value for skipping numbers - for i = 5, 1, -1 do — countdown with negative step - Building a multiplication table with string concatenation - Summing 1 to 100 with an accumulator variable Source Code: https://github.com/GoCelesteAI/learn-lua-in-neovim Timestamps: 0:00 - Introduction 0:12 - What You'll Learn (Preview) 0:44 - Creating the File & Header 1:00 - Basic Loop: Count 1 to 5 1:30 - Run: 1 2 3 4 5 2:00 - Step Value: Count by Twos 2:30 - Run: 2 4 6 8 10 3:00 - Countdown: 5 4 3 2 1 Go! 3:30 - Run: Countdown Output 4:00 - Multiplication Table 4:30 - Run: 7 x 1 = 7 ... 7 x 10 = 70 5:00 - Sum of 1 to 100 5:30 - Run: Sum = 5050 6:00 - Recap: Key Takeaways 6:32 - End Screen Key Takeaways: 1. for i = start, stop do repeats a block of code 2. Add a third value to set the step size 3. Negative step counts down from high to low 4. The loop variable i is local to the loop This is Episode 9 of the Learn Lua in Neovim series. New episodes cover while loops, functions, tables, and more — all coded inside Neovim. Taught by CelesteAI.
