After we do that, we can use a simple `for` **loop** to calculate the binomial coefficient by multiplying the values and dividing them by the loop index. Finally, we round the result to account for any **rounding errors** in the calculation, using `Math.round()`.

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.

The [binomial coefficient](https://en.wikipedia.org/wiki/Binomial_coefficient) is a mathematical concept that represents the number of ways to choose `k` items from `n` items without repetition and without order. In JavaScript, you can calculate the binomial coefficient using a simple function that loops through the values and calculates the result.

Before we loop through the values, we need to handle some **edge cases**, such as when `k` is less than `0`, greater than `n`, equal to `1` or `n - 1`, or when `n` or `k` is `NaN`. We also need to switch the values of `k` and `n - k` if `n - k` is less than `k` to optimize the calculation.
