Line length Open
`NaN` (Not-a-Number) is the only JavaScript value not equal to itself when comparing with any of the comparison operators. `NaN` is often the result of meaningless or invalid math computations, so it doesn't make sense for two `NaN` values to be considered equal.- Read upRead up

Aliases: line-length Parameters: linelength, codeblocks, tables (number; default 80, boolean; default true)
This rule is triggered when there are lines that are longer than the configured line length (default: 80 characters). To fix this, split the line up into multiple lines.
This rule has an exception where there is no whitespace beyond the configured line length. This allows you to still include items such as long URLs without being forced to break them in the middle.
You also have the option to exclude this rule for code blocks and tables. To
do this, set the code_blocks and/or tables parameters to false.
Code blocks are included in this rule by default since it is often a requirement for document readability, and tentatively compatible with code rules. Still, some languages do not lend themselves to short lines.
Line length Open
You can check for `NaN` values using the `Number.isNaN()` function. Note that this is different from the original , global `isNaN()`. Their difference lies in the fact that `isNaN()` forcefully converts its argument to a number, whereas `Number.isNaN()` doesn't. This is why `Number.isNaN()` is considered more robust and preferable in most cases.- Read upRead up
