eslint:
ESLint is highly configurable, allowing developers to define their own rules, extend existing ones, and create custom plugins. This flexibility makes it suitable for diverse coding styles and project requirements, enabling teams to enforce specific standards tailored to their needs.
prettier:
Prettier is opinionated and focuses solely on code formatting rather than code quality. It has limited configurability, which is intentional to ensure consistent formatting across projects. This makes it easy to use but may not cater to specific style preferences.
jshint:
JSHint offers some level of configurability through its options, but it is less flexible than ESLint. It allows for basic customization, such as enabling or disabling specific checks, making it easier to use for teams that prefer a straightforward approach without extensive configuration.
jslint:
JSLint is not configurable and enforces a strict set of rules. It is designed to promote a specific coding style and best practices, which may not suit all projects. Developers must adapt their code to fit JSLint's requirements, which can be limiting for some teams.

eslint:
ESLint excels in error detection, identifying a wide range of issues from syntax errors to potential bugs and anti-patterns. Its ability to integrate with IDEs and editors enhances real-time feedback during development, allowing developers to catch errors early in the coding process.
prettier:
Prettier does not focus on error detection in terms of code quality or potential bugs. Instead, it ensures that code is consistently formatted, which can indirectly reduce errors related to formatting but does not address logical or syntactical issues.
jshint:
JSHint provides basic error detection capabilities, focusing on common pitfalls and potential issues in JavaScript code. While it is effective for catching straightforward errors, it may not be as comprehensive as ESLint in identifying more complex problems.
jslint:
JSLint is strict and thorough in its error detection, often catching issues that other linters might overlook. However, its rigid nature can lead to false positives, which may frustrate developers who prefer a more flexible approach to error handling.

eslint:
ESLint has extensive integration capabilities with various development tools, including build systems, CI/CD pipelines, and popular code editors like VSCode and Atom. This makes it a versatile choice for modern JavaScript development environments.
prettier:
Prettier integrates well with many code editors and can be easily included in build processes. It is often used alongside ESLint to handle formatting, ensuring that code adheres to both style and quality standards.
jshint:
JSHint can be integrated into various development environments, but its integration options are more limited compared to ESLint. It is suitable for simpler setups but may not provide the same level of support for complex workflows.
jslint:
JSLint can be used as a standalone tool or integrated into some development environments, but it lacks the extensive support and plugins available for ESLint. Its integration capabilities are more basic, which may limit its usability in larger projects.

eslint:
ESLint has a large and active community, resulting in a rich ecosystem of plugins and shared configurations. This community support makes it easier for developers to find resources, share best practices, and extend the tool's functionality to meet specific needs.
prettier:
Prettier has gained significant popularity and has a strong community backing. It is often used in conjunction with ESLint, and its ecosystem includes various plugins and integrations that enhance its usability across different development environments.
jshint:
JSHint has a smaller community compared to ESLint, which may limit the availability of plugins and resources. While it is still a useful tool, developers may find fewer options for customization and support.
jslint:
JSLint has a dedicated following, but its strict approach has led to a more niche community. Resources and plugins are limited, which may hinder its adaptability for diverse projects and coding styles.

eslint:
ESLint has a moderate learning curve due to its extensive configurability and the need to understand its rule set. However, once familiar, developers can leverage its power to maintain high code quality effectively.
prettier:
Prettier is easy to learn and use, as it focuses solely on formatting. Developers can quickly adopt it without needing to understand complex configurations, making it accessible for teams looking to standardize code style.
jshint:
JSHint is relatively easy to learn, with a straightforward setup and fewer configuration options. Developers can quickly start using it to catch common issues without a steep learning curve.
jslint:
JSLint has a steep learning curve due to its strict rules and lack of configurability. Developers must adapt their coding practices to conform to its standards, which can be challenging for those used to more flexible tools.
