100daysofcode - Day 16
Hello friends, here we go, the 16th day is already here
. Let’s finish it successfully by taking some new information, to extend our existing knowledge in the Golang world. 


In today’s post, I’ll move a little bit out of track
and share with you some interesting information in String functions, that help us manipulate and deal with strings easily. 

So in this post we will explore
the strings package
, which gives us a lot of useful string-related functions to be used out of the box. 
- Example
package main
import (
"fmt"
s "strings"
)
var p = fmt.Println
func main() {
p("Contains: ", s.Contains("test", "es"))
p("Count: ", s.Count("test", "t"))
p("HasPrefix: ", s.HasPrefix("test", "te"))
p("HasSuffix: ", s.HasSuffix("test", "st"))
p("Index: ", s.Index("test", "e"))
p("Join: ", s.Join([]string{"a", "b"}, "-"))
p("Repeat: ", s.Repeat("a", 5))
p("Replace: ", s.Replace("foo", "o", "0", -1))
p("Replace: ", s.Replace("foo", "o", "0", 1))
p("Split: ", s.Split("a-b-c-d-e", "-"))
p("ToLower: ", s.ToLower("TEST"))
p("ToUpper: ", s.ToUpper("test"))
// Output
/*
Contains: true
Count: 2
HasPrefix: true
HasSuffix: true
Index: 1
Join: a-b
Repeat: aaaaa
Replace: f00
Replace: f0o
Split: [a b c d e]
ToLower: test
ToUpper: TEST
