/**
 * Checks if the given value is not null nor undefined.
 *
 * The main use of this function is to be used with TypeScript as a type predicate.
 *
 * @template T - The type of value.
 * @param {T | null | undefined} x - The value to test if it is not null nor undefined.
 * @returns {x is T} True if the value is not null nor undefined, false otherwise.
 *
 * @example
 * // Here the type of `arr` is (number | undefined)[]
 * const arr = [1, undefined, 3];
 * // Here the type of `result` is number[]
 * const result = arr.filter(isNotNil);
 * // result will be [1, 3]
