Lua with Neovim: Nested Tables — Tables Inside Tables, Chained Access & Averages | Episode 21

Real data is rarely flat. In this episode we explore nested tables — tables inside tables. We cover chained access with t.a.b, build arrays of tables to represent structured data, and compute averages by looping through nested records. Every keystroke is shown on screen with 3-second pauses so you can follow along at your own pace. What You'll Learn: - Nested tables — placing a table inside another table - Chained access — student.address.city reads deeply nested values - Modifying nested values through the chain - Arrays of tables — a list where each element is a dictionary - Looping through arrays of tables to compute averages - string.format for rounding decimal output Neovim Commands Used: - % — jump between matching braces - f. — find the next dot character - ; — repeat the last f/F find - 5G / 16G — jump to specific line numbers Timestamps: 0:00 Intro 0:12 Preview 0:44 Open file 1:25 Student table — name, grades, address 2:51 Chained dot access — print nested values 3:32 Modify nested city 3:57 Run student demo 4:16 Classroom — array of student records 5:42 Average loop — sum and divide 8:27 Run final program 8:56 Review — % match braces, f. find dot 9:25 Recap 9:57 Next: Table References vs Copies Practice code: https://github.com/GoCelesteAI/learn-lua-in-neovim This is Episode 21 of the Learn Lua in Neovim series. New episodes cover references, copies, libraries, and more — all coded inside Neovim. Taught by CelesteAI.
