JSLint is a tool used by web developers to ensure code quality. It was created by Douglas Crockford and released in 2002.
JSLint offers many options for developers to customize its behavior. Developers can choose which browser they are targeting, and JSLint will ensure that only features supported by that browser are allowed in the code. By default, JSLint will warn about any lines of code longer than 80 characters in length, but this limit can be raised if needed. In addition, several other settings can be customized to fit the preferences of individual teams or projects.
JSLint is a standard tool to minimize development time and maximize code quality.
JSLint was created by Douglas Crockford, who is also known for his work on JSON. JSLint can be run in your browser or integrated into your text editor.
It’s a good practice to keep JSLint open in a separate tab or window when you develop. Sometimes it feels annoying because it complains too much, but its strictness keeps me from writing bad code.
In the world of web development, there are multiple coding standards and style guides that dictate how code should be written. Different companies and organizations often use different style guides, and sometimes even different teams within the same company will use different ones. This can become a challenge when working on a team as coders may be used to a certain style and having to adapt to another can take time and effort that could be better spent elsewhere. To solve this problem, there are tools such as JSLint and JSHint that enforce a coding standard automatically.
What is JSLint?
What does it do?
It checks for errors like spelling mistakes, missing semicolons where they are required, trailing commas where they are not allowed, incorrect indentations, etc.. As well as performing style enforcement on things like variable name conventions, capitalization of functions and variables, placement of spaces etc..
Some useful options:
JSLint’s rules are largely based on Crockford’s own preferences, which have been documented as a set of coding conventions. Many of these conventions are also considered best practices by others in the industry, such as avoiding use of the eval function. Some other rules are more subjective and some have drawn criticism from programmers who disagree with them, such as requiring functions to be declared before they are used and requiring parentheses around statements even when they are not needed for clarity.
Because of this subjectivity, JSHint was created in 2011 as an alternative tool that can be configured by the user to enforce different coding style rules than JSLint does by
JSLint was developed by Douglas Crockford. It is an open-source project hosted on GitHub and distributed under the MIT License.
The name “JSLint” may be confusing because it suggests that it is similar to tools such as JSHint and ESLint, which are actively maintained and allow configuring the rules being enforced. JSLint, however, requires that the source code strictly conforms to its own set of rules which cannot be configured. The website states “If you want to enforce your own coding conventions, then JSLint is not for you,” and instead recommends the use of JSHint or ESLint.
