How to use Escape Characters to Log Quotes in JavaScript?

In JavaScript, escape characters are used to include special characters like quotes within strings without causing syntax errors.

By placing a backslash (`\`) before a quote, you can ensure that the quote is treated as part of the string rather than as a delimiter. This is essential for correctly logging strings that contain both single and double quotes.

Our aim is that we want to print in the console like:

""Geeks" for "Geeks" is 'the' best 'platform'"

To print quotes, using escape characters we have two options:

Using Quotes Without Escaping Characters

In JavaScript, you can use single quotes to define a string and include double quotes inside it without needing escape characters. This allows you to easily print double quotes within the string while avoiding syntax errors.

Example: In this example, string literals using single and double quotes. It compares strings for equality and shows how to include quotes inside strings using escaping or different quote types.

// Using single quotes for string
let s1 = 'Geeks for Geeks';

// Using double quotes for string
let s2 = "Geeks for Geeks";

// Both s1 and s2 are the same
console.log((s1 === s2)); // true
console.log(s1); // Geeks for Geeks
console.log(s2); // Geeks for Geeks

// Single quotes for string, double quotes inside
let str = '"Geeks" "FOR" Geeks';
console.log(str); // "Geeks" "FOR" Geeks

// Double quotes for string, single quotes inside
str = "'Geeks' \'FOR\' Geeks";
console.log(str); // 'Geeks' 'FOR' Geeks

true
Geeks for Geeks
Geeks for Geeks
"Geeks" "FOR" Geeks
'Geeks' 'FOR' Geeks

Using Escape Characters for Double Quotes

In JavaScript, you can use double quotes to define a string and include single quotes inside it without needing escape characters. This approach allows you to print single quotes within the string seamlessly while maintaining correct syntax.

Example: Using escape sequences - If you have begun the quotes using \' then you must end the quote also using \' and vice versa.

// Using escape sequences - here you can
// use single as well as double quotes
// within the string to print quotation
let str = 'Geeks \'FOR\' Geeks';
console.log(str); // Geeks 'FOR' Geeks

str = "Geeks \"FOR\" Geeks";
console.log(str); // Geeks "FOR" Geeks

str = '\'Geeks \"FOR\" Geeks\'';
console.log(str); // 'Geeks "FOR" Geeks'

str = "\"\"Geeks\" for \"Geeks\" is \'the\' best \'platform\'\"";
console.log(str); // ""Geeks" for "Geeks" is 'the' best 'platform'"

Geeks 'FOR' Geeks
Geeks "FOR" Geeks
'Geeks "FOR" Geeks'
""Geeks" for "Geeks" is 'the' best 'platform'"
