Println vs Printf vs Print in Go

Question

I come from a land of JS and have mostly used things like console.log or console.error

Now, the tutorial I am following, the instructor over there did something like this

package main  import "fmt"    func main() {      var FirstName = "Varun"     var lastName = "bindal"      fmt.Println(FirstName, lastName)     fmt.Printf("%T", FirstName) } 

Here he did PrintF to check type instead of Println. Initially, I thought that println prints in new Line so I changed my

fmt.Printf("%T", FirstName) 

to

fmt.Println("%T", FirstName) 

but this logged %T Varun instead of telling me the type.

I went to their site to figure it out and was either unable to comprehend it or wasn't able to find it out.

Googling lead me know that there are three ways to log/print in Go

1. Println
2. Printf
3. Print

So, If someone call tell the difference between three of them?

Answer 1

• Printf - "Print Formatter" this function allows you to format numbers, variables and strings into the first string parameter you give it
• Print - "Print" This cannot format anything, it simply takes a string and print it
• Println - "Print Line" same thing as Printf() however it will append a newline character\n
