JavaScript console Methods Quick Guide
So, while implementing logging in Next.js, I stumbled upon the console rabbit hole. I used to use console.log and error quite regularly, but wasn’t aware of other methods natively provided by JavaScript. Let’s dive into it.
console.error → Shows an error message (shown in red)
console .warn → Shows a warning message (shown in yellow)
console.info → Shows an informative message, such as what port we are working on.
console.log → Used for general logging that is temporary.
console.debug → Shows a message to the console with the log level debug, i.e. more detailed information that is relevant only to the developer to investigate an issue and is hidden otherwise.
console.table → Shows data of an array/object as a table. Eg: console.table([“apples”, “oranges”, “bananas”]);
console.time → Allows you to set a timer to see how long a task takes to be completed.
Be sure to use a git pre-commit hook or plugin to check methods or keywords, such as consoles, that you don’t want to appear before the production release.
