How to Fix SyntaxError: Unexpected Token in JavaScript

Encountering a "SyntaxError: Unexpected token" in JavaScript typically signifies the presence of a character or symbol that the JavaScript engine does not expect, often due to typos or syntax mistakes. To resolve this, developers should examine the error log for specifics like the line and character position, which can point to the problematic token. Common causes include missing or extra characters, misuse of reserved keywords, improper string delimiters, and incorrectly formatted JSON data. Adopting good coding practices, such as using tools like ESLint and writing clean, well-indented code, can help prevent such errors. Additionally, error management tools like Rollbar can automate error monitoring and triaging, making it easier to track, analyze, and manage errors in real-time, thereby enhancing confidence in deploying production code.
