The javascriptatan2 () method returns an angle between the x axis and the point (x, y. This function has two parameters: the first parameter specifies the X coordinate of the vertex, and the second parameter specifies the Y coordinate of the vertex. Note that the parameter order of this function is passed before the X coordinate. This article describes the basic syntax and examples of the atan2 function. For more information about the coders, see. The atan2 method returns the angle (in radians) from the X axis to the (y, x) Point ).
Basic Syntax:
Math.atan2(y, x)
