var str1 = "Hello there!"; //or var str2 = 'Hello there!';
There can be use cases when you need to include a double quote or a single quote inside the string.
To achieve this, we can use the escape character '\' as shown below
var str1 = "\"Hello there!\"- Obi Wan Kenobi"; // "Hello there" - Obi Wan Kenobi var str2 = '\'Urr Arrgghh Urr\' - Chewbacca' // 'Urr Arrgghh Urr'- Chewbacca
How to display '\' in string since '\' is considered as escape sequence? Even in this case, the escape sequence can be used to display '\'
var str3 = "1\\2 is perfectly balanced"; /* 1\2 is perfectly balanced */
