In JavaScript, you can use escape sequences to add special characters to strings. Here is a list of some common escape sequences:
\': Single quote\": Double quote\\: Backslash\n: Newline\r: Carriage return\t: Tab\b: Backspace\f: Form feed
For example:
[dm_code_snippet background="yes" background-mobile="yes" slim="no" line-numbers="no" bg-color="#abb8c3" theme="dark" language="php" wrapped="no" height="" copy-text="Copy Code" copy-confirmed="Copied"]Copy code let str = "This is a string\nWith a newline."; console.log(str); // Output: "This is a string // With a newline."
[/dm_code_snippet]
You can also use Unicode escape sequences to represent any Unicode character. For example:
[dm_code_snippet background="yes" background-mobile="yes" slim="no" line-numbers="no" bg-color="#abb8c3" theme="dark" language="php" wrapped="no" height="" copy-text="Copy Code" copy-confirmed="Copied"]Copy code let str = "\u00A9"; // Copyright symbol (©) console.log(str); // Output: "©"
[/dm_code_snippet]
Note that you can also use template literals (enclosed in backticks) to include special characters in strings without using escape sequences. For example:
[dm_code_snippet background="yes" background-mobile="yes" slim="no" line-numbers="no" bg-color="#abb8c3" theme="dark" language="php" wrapped="no" height="" copy-text="Copy Code" copy-confirmed="Copied"]Copy code let str = `This is a string With a newline.`; console.log(str); // Output: "This is a string // With a newline."
[/dm_code_snippet]
Here are some additional examples of using escape sequences in JavaScript:
[dm_code_snippet background="yes" background-mobile="yes" slim="no" line-numbers="no" bg-color="#abb8c3" theme="dark" language="php" wrapped="no" height="" copy-text="Copy Code" copy-confirmed="Copied"]Copy code
let str = 'This is a string with a single quote (\') character.'; console.log(str); // Output: "This is a string with a single quote (') character." let str = "This is a string with a double quote (\") character."; console.log(str); // Output: "This is a string with a double quote (") character." let str = "This is a string with a backslash (\\) character."; console.log(str); // Output: "This is a string with a backslash (\) character." let str = "This is a string\twith a tab character."; console.log(str); // Output: "This is a string with a tab character." let str = "This is a string\bwith a backspace character."; console.log(str); // Output: "This is a stringwith a backspace character." let str = "This is a string\fwith a form feed character."; console.log(str); // Output: "This is a string // with a form feed character."
[/dm_code_snippet]
Note that you can use escape sequences not just in string literals, but also in string templates and string concatenation. For example:
[dm_code_snippet background=”yes” background-mobile=”yes” slim=”no” line-numbers=”no” bg-color=”#abb8c3″ theme=”dark” language=”php” wrapped=”no” height=”” copy-text=”Copy Code” copy-confirmed=”Copied”]
let x = 5;
let y = 10;
let str = `The value of x is ${x}\nThe value of y is ${y}`;
console.log(str);
// Output: "The value of x is 5
// The value of y is 10"
let str = "The value of x is " + x + "\nThe value of y is " + y;
console.log(str);
// Output: "The value of x is 5
// The value of y is 10"
