explicit-boolean-comparison-plugin

A Deno lint plugin that enforces explicit boolean comparisons by disallowing the use of the ! shorthand for boolean negation. This rule helps improve code readability by requiring an explicit comparison (e.g., variable === false) in conditional statements.

Note

If it were up to me, I’d launch a strike to wipe out the ! shorthand that turns code into unreadable chaos. But until I can secure the necessary military funding, here’s a lint plugin as a peace offering.

Example

if (!flag) { // ⚠️ Avoid using '!' shorthand for boolean negation to improve readability. Use an explicit comparison instead (e.g., flag === false).
  console.log("Flag is false");
}

Usage

Add the following block to your deno.json file:

{
  "lint": {
    "plugins": [
      "jsr:@miguelripoll23/explicit-boolean-comparison-plugin"
    ]
  }
}
