Tip
Use template literals with backticks in modern JS for multi-line strings to avoid manual newline escaping.
Did You Know?
The backslash character is the universal escape prefix used in JavaScript string literals.
JavaScript String Encoding is the process of using escape sequences to represent characters that are difficult or impossible to include directly in a string literal. This includes characters like newlines, tabs, or the very quote characters used to define the string itself. By using these sequences, developers ensure that the code is interpreted correctly by the browser and prevents unexpected termination of string literals, which would lead to syntax errors or execution bugs.
Best Practice
Always escape user-provided content before inserting it into a JavaScript string to prevent XSS attacks.
