Learn Lua in Neovim: Tables as Arrays — 1-Based Indexing, Insert, Remove & Length | Episode 17

Tables are the heart of Lua. In this episode we create an array-style table with curly braces, learn that Lua counts from one (not zero!), use the hash operator for length, add items with table.insert, remove items with table.remove, and loop through everything with a for loop. Every keystroke is shown on screen with 3-second pauses so you can follow along at your own pace. Source code: https://github.com/GoCelesteAI/learn-lua-in-neovim What You'll Learn: - local fruits = { "apple", "banana", "cherry" } — table constructor - fruits[1] — 1-based indexing (not zero!) - #fruits — the length operator - table.insert(fruits, "elderberry") — append to end - table.remove(fruits, 2) — remove at index (shifts remaining) - for i = 1, #fruits do — loop through the array Timestamps: 0:00 Intro 0:12 Preview 0:44 Create and Access — table constructor, index 1, #length 2:20 Run: First fruit, third fruit, count 2:33 Insert and Remove — table.insert, table.remove 4:10 Run: Insert elderberry, remove banana 4:23 Loop Through Array — for with #length 5:37 Run: All fruits listed 5:50 Code review 5:58 Recap Key Takeaways: 1. Curly braces create a table — the only data structure in Lua 2. Lua arrays start at index 1, not 0 3. Hash gives the array length — #fruits 4. table.insert and table.remove modify the list dynamically This is Episode 17 of the Learn Lua in Neovim series. New episodes cover table operations, dictionaries, nested tables, and more — all coded inside Neovim. Taught by CelesteAI.
