/**
 * Calculates the Euclidean distance between two points in 2D space.
 * Returns 0 if the result is not finite.
 *
 * @param x1 - X coordinate of first point
 * @param y1 - Y coordinate of first point
 * @param x2 - X coordinate of second point
 * @param y2 - Y coordinate of second point
 * @returns The distance between the two points
 *
 * @example
 * ```ts
 * distance(0, 0, 3, 4); // 5
 * distance(1, 1, 4, 5); // 5
 * ```
