Go Arrays

Description

An array is a numbered sequence of elements of a specific length. The length is part of the array's type, so arrays cannot be resized. This makes them less common than Slices.

Pros & Cons

When to Use

When you need a fixed-size buffer or lookup table.

Example

Declaring and initializing arrays.

var a [2]string
a[0] = "Hello"
a[1] = "World"

primes := [6]int{2, 3, 5, 7, 11, 13}
fmt.Println(primes)

Best Practices

Use arrays mostly as building blocks for slices. In 99% of app code, use Slices.
