What are slices in Go and how do they work?

What are slices in Go and how do they work?

Slices in Go are a flexible and powerful way to work with sequences of data. They are built on top of arrays and provide a dynamic size, allowing you to easily add or remove elements.

Can you explain how to create a slice?

Sure! You can create a slice using the make function or by slicing an existing array. For example, mySlice := make([]int, 0) creates an empty slice of integers.

How do I append elements to a slice?

You can use the built-in append function. For example, mySlice = append(mySlice, 1) adds the integer 1 to the slice.

What happens if I exceed the capacity of a slice?

If you exceed the capacity, Go automatically allocates a new, larger array, copies the existing elements, and appends the new element.

Can slices hold different types of data?

No, slices in Go are homogeneous, meaning they can only hold elements of the same type.
