Basic Knowledge: String Escaping in JavaScript

In JavaScript, strings are defined using single quotes ('), double quotes ("), or backticks (`). If your string content contains the same character used to define it, you must "escape" it using a backslash (\).

Common Escape Sequences

\': Single quote
\": Double quote
\n: Newline
\r: Carriage return
\t: Tab
\\: Backslash
\`: Backtick (Template literal)

Why Escape Strings?

Prevent Syntax Errors: Unescaped quotes can prematurely end a string, causing the JavaScript engine to throw an error.
Handle Multi-line Data: Convert newlines into \n to keep your code on one line if necessary.
Data Integrity: Ensure that special characters are stored and processed correctly without being misinterpreted as code instructions.

FAQ

Q: Does this tool store my data?
A: No. All calculations and transformations are performed locally in your browser. We never see or store your input.

Q: Can I use this for template literals?
A: Yes! You can choose to escape backticks (`) specifically for template literal use cases.

Q: Is there any limit to the string length?
A: There is no strict limit, but extremely large strings (several MBs) might slow down your browser's performance.

Q: What characters are escaped by default?
A: By default, the tool escapes backslashes, newlines, carriage returns, tabs, and all three types of quotes (single, double, and backticks).
