It returns a new array containing the arctangent values, expressed in radians. The input array is specified using `this: input`. Examples are provided demonstrating usage with different input values, such as -5, 0, and 5. Additionally, code examples in both JavaScript and Python showcase creating and plotting a sequence of points and their corresponding arctangent values using libraries to show graphical results.\n"]]
