Println, Printf, or Print: Which Go Output Function is Right for You?

Println vs Printf vs Print: Unlocking the Power of Go's Output Functions

As a JavaScript developer transitioning to Go, you may encounter the concepts of Println, Printf, and Print. Understanding the distinctions between these functions is crucial for effective debugging and output management.

Printf, the "Print Formatter," enables you to format and insert variables into a string. Its syntax includes a format string followed by the variables to be formatted. For example, the code fmt.Printf("%T", FirstName) attempts to format the value of FirstName as a type using "%T."

Println, the "Print Line," is similar to Print. However, it automatically appends a newline character (n) to the output, creating a new line. This is useful for separating lines in console output.

Print, the basic "Print" function, simply prints the string provided as the first parameter. It does not format the value or append a newline.

In summary:

• Use Println to print values with a newline character.
• Use Print for simple string output without formatting or line breaks.
• Use Printf for formatting and inserting values into a string.
