Rule: use-isnan
Enforces use of the isNaN()
function to check for NaN references instead of a comparison to the NaN
constant.
Rationale
Since NaN !== NaN
, comparisons with regular operators will produce unexpected results.
So, instead of if (myVar === NaN)
, do if (isNaN(myVar))
.
Config
Not configurable.
Examples
"use-isnan": true
