While deno_lint is integrated into the Deno runtime and can be used via the Deno CLI, it is also available as a standalone binary. This tutorial explains how to install deno_lint on Ubuntu 24.04.

printf "var x = 1;\nconsole.log(x);" > test.js

To use deno_lint, run the command dlint run followed by the name of the JavaScript or TypeScript file. For example:

dlint run test.js

The command will analyze the code and provide feedback on any detected issues. Output:
