What happened?
There is a string in the code which is not terminated. String literals need to be enclosed by single (‘) or double (“) quotes. JavaScript sees no difference between single-quoted strings and double-quoted strings.
Example 1: In this example, the single quotes are used and the string is not terminated, So the error has occurred.
Javascript
let GFG_str = 'Thisis GeeksForGeeks';console.log(GFG_str); |
Output(In console):
SyntaxError: Unterminated string constant
Example 2: In this example, the double quotes are used and the string is not terminated, So the error has occurred.
Javascript
let GFG_str = "Thisis GeeksForGeeks";console.log(GFG_str); |
Output(In console):
SyntaxError: Unterminated string constant
