Problem

How do I check if a string is a substring of another string in Go?
For example, I want to check someString.contains("something").

Use the function Contains from the strings package.

import (
    "strings"
)
strings.Contains("something", "some") // true

import (
    "strings"
)
strings.Contains("something", "some") // true
