Eslint-Disable-Next-Line Multiple

Introduction

When developing JavaScript code, developers often encounter situations where they need to disable specific eslint rules for a particular line of code or a section of code. This can be accomplished using the eslint-disable comment directive. However, if there are multiple rules that need to be disabled on the same line or section of code, this can lead to very messy and cumbersome code. In these situations, the eslint-disable-next-line directive can be used to disable multiple rules on the next line of code. This feature is very useful for developers who need to disable multiple rules and keep their code clean and readable.

How it works

The eslint-disable-next-line directive works by telling eslint to ignore the next line of code when checking for rule violations. This allows developers to disable specific rules on a per-line basis without having to disable all rules for the entire file or directory.

Here is an example of how to use the eslint-disable-next-line directive to disable multiple rules on the next line of code:

// eslint-disable-next-line no-unused-vars, no-undef
const myUnusedVar = undefined;

In this example, the no-unused-vars and no-undef rules are disabled on the next line of code. This allows developers to define the myUnusedVar variable without causing eslint to throw errors or warnings.

Conclusion

The eslint-disable-next-line directive is a very useful feature for developers who need to disable multiple rules on a specific line of code. It allows developers to keep their code clean and readable by avoiding messy and cumbersome eslint-disable directives. When using this feature, it is important to disable only the rules that are absolutely necessary, and to avoid disabling rules across large sections of code or entire files. By using this feature sparingly and strategically, developers can keep their code clean, readable, and free from eslint errors and warnings.
