📝 Description
Discover the latest feature in Go 1.23 that's changing how we handle iterations: Custom Iterators! This video is tailored for developers eager to expand their toolkit with Go's new iteration capabilities. Here's what we'll cover:
• Understanding Range Iteration: Learn what range iteration means in Go and how it's traditionally used with slices and maps.
• Custom Iterators: Dive into how Go 1.23 allows you to create custom iterators for any data structure, not just the built-in types.
• Practical Examples: From simple to complex, see custom iterators in action. We'll create an iterator for a slice with transformation functions using the new iter package.
• Advanced Usage with iter.Seq and iter.Seq2: Explore how to handle single and dual value iterations with custom logic applied on the fly.
• Why Custom Iterators Matter: Understand the use cases where custom iterators can significantly enhance your code's readability and functionality, especially if you're into library development.
