Arrays & Slices (Append, Make, Copy & Slicing) - Go Tutorial for Beginners #9

Master Go's collection types - Arrays and Slices! In this lesson, you will learn: ✓ Fixed-size arrays and their value semantics ✓ Dynamic slices and reference behavior ✓ Slicing with colon notation ✓ Append and make functions ✓ Copy for independent slices ✓ Nil vs empty slices ⏱️ Timestamps: 0:00 - Introduction 0:24 - Arrays (Fixed Size) 2:09 - Slices (Dynamic) 3:46 - Append and Make 5:38 - Copy and Nil Slices 7:27 - Recap 7:57 - End 💻 Source Code: https://github.com/GoCelesteAI/go_slices 📝 Code Highlights: // Array (fixed size, value type) var arr [5]int fruits := [3]string{"apple", "banana", "cherry"} // Slice (dynamic, reference type) nums := []int{10, 20, 30, 40, 50} fmt.Println(nums[:3]) // First 3 fmt.Println(nums[2:]) // From index 2 // Append nums = append(nums, 60, 70) nums = append(nums, more...) // Make with length and capacity buffer := make([]int, 5, 10) // Copy (creates independent slice) dst := make([]int, len(src)) copy(dst, src) 📺 Previous: Lesson 8 - Loops: for 📺 Next: Lesson 10 - Maps #Go #Golang #GoTutorial #LearnGo #Programming #Arrays #Slices #GoProgramming
