SyntaxError: string literal contains an unescaped line break

Message

Error type

What went wrong?

There is an unterminated string literal somewhere. String literals must be enclosed by single (') or double (") quotes. JavaScript makes no distinction between single-quoted strings and double-quoted strings. Escape sequences work in strings created with either single or double quotes. To fix this error, check if:

• you have opening and closing quotes (single or double) for your string literal,
• you have escaped your string literal correctly,
• your string literal isn't split across multiple lines.

Examples

Multiple lines

You can't split a string across multiple lines like this in JavaScript:

Instead, use the + operator, a backslash, or template literals. The + operator variant looks like this:

Or you can use the backslash character ("\") at the end of each line to indicate that the string will continue on the next line. Make sure there is no space or any other character after the backslash (except for a line break), or as an indent; otherwise it will not work. That form looks like this:

Another possibility is to use template literals.
