Go Programming Course [03]: Arrays, Slices, Strings, Runes & Bytes (Composite Types Explained)
Learn how the 𝐆𝐨 𝐏𝐫𝐨𝐠𝐫𝐚𝐦𝐦𝐢𝐧𝐠 𝐋𝐚𝐧𝐠𝐮𝐚𝐠𝐞 handles data structures! In this third episode, we dive deep into 𝐂𝐨𝐦𝐩𝐨𝐬𝐢𝐭𝐞 𝐓𝐲𝐩𝐞𝐬. If you want to write efficient Go code, you must understand how Go manages memory under the hood.
I break down the critical differences between 𝐀𝐫𝐫𝐚𝐲𝐬 (fixed size) and 𝐒𝐥𝐢𝐜𝐞𝐬 (dynamic size), how 𝐒𝐭𝐫𝐢𝐧𝐠𝐬 are just read-only byte slices, and the fundamental difference between Compile-Time and Runtime execution.
𝐈𝐧 𝐭𝐡𝐢𝐬 𝐯𝐢𝐝𝐞𝐨, 𝐲𝐨𝐮 𝐰𝐢𝐥𝐥 𝐥𝐞𝐚𝐫𝐧:
𝟏. 𝐀𝐫𝐫𝐚𝐲𝐬 𝐯𝐬. 𝐒𝐥𝐢𝐜𝐞𝐬: Why Arrays are rigid and how Slices provide dynamic flexibility.
𝟐. 𝐔𝐧𝐝𝐞𝐫 𝐭𝐡𝐞 𝐇𝐨𝐨𝐝: How a Slice acts as a reference to an underlying Array.
𝟑. 𝐒𝐭𝐫𝐢𝐧𝐠𝐬, 𝐑𝐮𝐧𝐞𝐬 & 𝐁𝐲𝐭𝐞𝐬: The truth about how Go stores text and characters.
𝟒. 𝐌𝐞𝐦𝐨𝐫𝐲 𝐌𝐚𝐧𝐚𝐠𝐞𝐦𝐞𝐧𝐭: How data structures behave differently in Go compared to other languages.
𝟓. 𝐂𝐨𝐦𝐩𝐢𝐥𝐞-𝐭𝐢𝐦𝐞 𝐯𝐬. 𝐑𝐮𝐧𝐭𝐢𝐦𝐞: Understanding when your code is checked versus when it executes, and why it matters for performance.
