Quotes

A raw string literal is a string in which the escape characters like \n, \t or \" are not processed.

C++

• Single quote ('): single character
• Double quote ("): string

Raw string literal:

R"delimiter(raw_characters)delimiter"

delimiter is optional. One common usecase is to create ProtoBufs in tests:

R"pb({
 ...
})pb";

Java

• Single quote ('): single character
• Double quote ("): string
• Text blocks:

String foo = """
    bar
    baz
""";

Python

Single quotes (') and double quotes (") are quivelent.

Backtick quoting is generally non-useful and gone in Python 3.

Multiline strings: triple quotations using either single quotes ''' or double quotes """.

Python docstrings (triple quotations using either single quotes ''' or double quotes """) are the string literals that appear right after the definition of a function, method, class, or module.

def foo():
    '''This is the docstring.'''
    pass

JavaScript

Single quotes (') and double quotes (") are quivelent.

Template literals (Template strings) (`):

• allow for multi-line strings.
• string interpolation, e.g. hello ${name}!.

Go

• Double quote ("): need to escape special characters, e.g. "\n" is a single character
• backtick (`): raw string literals, no escape.
