How to Fix Unexpected Token Else in My JavaScript Code?

JavaScript is a versatile language, but it can sometimes be a bit tricky, especially when dealing with various errors like the 'Unexpected Token Else' error. If you've landed here, it's likely that you've encountered this particular issue in your code. Let's dive into what causes this error and how you can fix it.

Understanding the Error

The 'Unexpected Token Else' error is a common JavaScript syntax error that typically occurs when the if statement is not properly closed or formatted. JavaScript expects specific tokens (characters or sets of characters that are fundamental units of a programming language) at certain places, and when the else keyword appears unexpectedly, it breaks the flow, resulting in this error.

Common Causes

Missing Closing Bracket for if Statement: Every if condition must be properly enclosed within curly braces { }. If you forget to close these braces, the interpreter can't correctly parse the rest of your code.

Misplaced or Extra Semicolon: Sometimes, an extra semicolon after an if statement can end the statement prematurely, making the else appear out of context.
