Frequently Asked Questions

How do I escape a quote in a JavaScript string?

Inside a single-quoted string escape ' as \'; inside a double-quoted string escape " as \"; inside a template literal escape the backtick ` as \` and ${ as \${. This tool escapes all quote styles plus the backslash so the result is safe in any JS string literal.

What characters does JavaScript string escaping cover?

The backslash itself (\\), the three quote characters (' " `), and the whitespace controls newline (\n), carriage return (\r) and tab (\t). Backslash must be escaped first, otherwise it would corrupt the following escape sequences.

Is JavaScript escaping the same as JSON escaping?

They overlap but differ. JSON only allows double-quoted strings and a fixed set of escapes; JavaScript also has single quotes, template-literal backticks and ${} interpolation. Use JavaScript Escape for code you paste into a .js file, and JSON Escape for values going into a .json document.

Does this run on a server?

No. Escaping and unescaping happen entirely in your browser with plain JavaScript — no upload, no logging. Safe for embedding API keys or config strings into source.

Can I unescape a JavaScript string back to plain text?

Yes. Click Unescape and the tool reverses the literal escapes — \n becomes a real newline, \' becomes ', and \\ becomes a single backslash — recovering the original text.

🎓 Pro Tips

  • Tip 1: Escape the backslash first — it must be doubled before other sequences, or it will corrupt the following escape.
  • Tip 2: Use JavaScript Escape for .js source and JSON Escape for .json values; template-literal backticks and ${} are JS-only.
  • Tip 3: Prefer template literals for multi-line strings so you don't have to escape every newline as \n.
