strings.Contains

Checking for substrings

Check if a string contains a substring:

s := "Hello, World!"
fmt.Println(strings.Contains(s, "World"))  // true
fmt.Println(strings.Contains(s, "world"))  // false (case-sensitive)

The search is case-sensitive. For case-insensitive matching, convert both strings to lowercase first using strings.ToLower, then check containment.
