/**
|
|
* Adds two numbers while safely handling `NaN` values.
|
|
*
|
|
* This function takes two numbers and returns their sum. If either of the numbers is `NaN`,
|
|
* the function returns `NaN`.
|
|
*
|
|
* @param {number} value - The first number to add.
|
|
* @param {number} other - The second number to add.
|
|
* @returns {number} The sum of the two numbers, or `NaN` if any input is `NaN`.
|
|
*
|
|
* @example
|
|
* const result1 = add(2, 3); // result1 will be 5
|
|
* const result2 = add(5, NaN); // result2 will be NaN
|
|
* const result3 = add(NaN, 10); // result3 will be NaN
