Did You Know?
JavaScript strings are internally represented as UTF-16, which is why some emojis require two escape sequences.
Tip
Use backticks (template literals) in modern JS to handle multi-line strings without needing manual line-break escaping.
JavaScript string encoding is the process of converting characters that have special meaning in the language—such as quotes ('), backslashes (\), and line breaks—into escape sequences. This also includes converting non-ASCII characters into Unicode (\uXXXX) or Hex (\xXX) notation. This ensures that strings can be safely transmitted and embedded within source code without being misinterpreted by the JavaScript engine as code instructions or causing syntax errors. Decoding reverses this process, turning those sequences back into human-readable text.
Best Practice
Always escape the backslash character itself (\\) if you want it to appear as a literal character in your string.

Q: What is the difference between Unicode and Hex escaping? A: Hex escapes (\xXX) are used for 8-bit character codes, while Unicode escapes (\uXXXX) are for 16-bit characters, covering a much wider range of global symbols.
