eslint-plugin-arithmetic

ESLint rule which calculates out some simple arithmetics.
Useful for when you know what you want to write, but you cannot be bothered to calculate it.

• Supports +, -, *, /, %, |
• Supports Math.floor(), Math.ceil(), Math.round()
• Recommended for use in an editor which autofixes your code when you save the file

Installation

# Shell
npm install -D eslint-plugin-arithmetic

// eslintrc.js
{
    "plugins": ["arithmetic"],
    "rules": {
        "calc": "warn"
    }
}

But what if I don't want to calculate some stuff?

Sometimes it is useful to have things like 3600 * 1000 in your code to make it easier to understand that you mean 1 hour. Maybe you will find the package ms useful.

You can also put // eslint-disable-line arithmetic/calc at the end of a line to not calculate an expression.

If you find this cumbersome, this package might not be for you.
