unicorn/prefer-math-min-max

To read size > 100 ? 100 : size, you have to work out which way the comparison goes and which branch wins. Math.min(size, 100) says it by name.

The rule only reports a variable compared with a number, such as 100 or -1. Two variables could hold strings, dates or bigints, and Math.min() would turn those into numbers or throw.

Configure

Off by default. To turn it on:

[lint.rules]
"unicorn/prefer-math-min-max" = "error" # or "warn"

Examples

Reported:

const width = size > 100 ? 100 : size;
const volume = level < 0 ? 0 : level;

Not reported:

const width = Math.min(size, 100);
const volume = Math.max(level, 0);

const latest = first > second ? first : second;
