Question

What is the difference between backticks (``) & double quotes ("") in golang?

Answer 1

In quotes "" you need to escape new lines, tabs and other characters that do not need to be escaped in backticks ``. If you put a line break in a backtick string, it is interpreted as a '\n' character, see https://golang.org/ref/spec#String_literals

Thus, if you say \n in a backtick string, it will be interpreted as the literal backslash and character n.

a := "\n" // This is one character, a line break. b := `\n` // These are two characters, backslash followed by letter n. 

Answer 2

Backtick strings are analogs of multiline raw string in Python or Scala: r""" text """ or in JavaScript:

String.raw`Hi\u000A!` 

They can:

1. Span multiple lines.

2. Ignore special characters.

They are useful:

1. For putting big text inside.

2. For regular expressions when you have lots of backslashes.

3. For struct tags to put double quotes in.
