As with any programming language, code optimization plays a crucial role in improving the efficiency and speed of GO programs. Optimizing GO code involves identifying bottlenecks, reducing unnecessary operations, and utilizing language-specific features to enhance performance. In this article, we will explore several examples of code optimization techniques in GO, along with practical illustrations to demonstrate their effectiveness.

1. Avoiding String Concatenation with strings.Builder:

String concatenation using the + operator in a loop can result in inefficient code due to the immutability of strings in GO. The strings.Builder type provides a more efficient way to concatenate strings dynamically. Here's an example:

// Inefficient Concatenation
result := ""
for i := 0; i < len(array); i++ {
    result += array[i]
}

// Efficient concatenation using strings.Builder
var builder strings.Builder
for i := 0; i < len(array); i++ {
    builder.WriteString(array[i])
}
result := builder.String()
