Best Practices to avoid and fix Parsing Error Unexpected Tokens in your code

As a developer, we all know how frustrating it can be to receive an unexpected error message while coding. And one of the most common errors that we encounter is the Parsing Error Unexpected Token.

Parsing Error Unexpected Token occurs when you have written a code instruction that your JavaScript compiler cannot understand. A token refers to any piece of code such as a keyword, function name or variable name, and if it has been incorrectly used in your code or placed in the wrong context, then you will receive this error message.

The good news is that fixing parsing errors is relatively straightforward. In this article, we will discuss some best practices to avoid and fix Parsing Error Unexpected Tokens in your code.

1. Check for missing or misplaced syntax

One of the primary reasons why parsing errors occur is due to simple syntax mistakes like leaving out a comma or parenthesis which are essential to structure your code correctly. Ensure that you check your codes carefully for such syntax errors before compiling them.

2. Use Proper formatting and indentation

Following proper formatting and indentation is essential not just for aesthetic purpose but also helps in identifying syntax errors that might otherwise go unnoticed. Leaving out indentations might lead to unexpected tokens being identified by the compiler.

3. Keep extra whitespace at bay

Browsers interpret extra whitespace within their HTML source codes as part of their output string resulting in parsing error messages afterward. Minimizing and keeping only helpful white spaces throughout the text can significantly help avoid receiving such an issue.

4. Avoid mixing up quotation marks

Javascript requires consistency where quotation marks are concerned, using double quotes at times when single quotes would suffice could compromise readability resulting in parser problems detecting unexpected characters within lines of JS codes/chunks.

5) Always update & take note of ES6 best practices

ES6 added many new features like arrow functions, classes etc which resulted into new/updated syntax styles meanwhile some old functionalities get modifiers too from method declarations turning regular functions into object methods. Be informed of these changes and always try to follow ES6 recommended syntaxes as much as possible too.

In conclusion, Parsing Error Unexpected Tokens can be frustrating to deal with, but with practice and attention to detail, they can be avoided. Always ensure that you are using consistent best practices in your coding processes, properly formatting and indenting your code structure, as well as double-checking for simple mistakes in syntax, characters or incomplete pieces. Remember it is always better to take more time avoiding such discrepancies than later on fixing them.
