| add(p1, p2) | Adds the x and y values of the two points and returns a new point. |
| encloses(r1, r2, allowSharedEdges) | Calculates whether or not r2 is completely enclosed by r1. |
| extend(o1, o2, keys) | Equivalent of Object.assign, which IE11 does not support. |
| fastTrim(s) | Trims whitespace from the given string. |
| getsert(map, key, valueGenerator) | Get, or insert then get, a value from the map. |
| gradient(p1, p2) | Calculates the gradient of a line between the two points. |
| insertSorted(value, array, comparator, sortDescending) | Inserts the given value into the given array at a sorted location. |
| intersects(r1, r2) | Calculates whether or not the two rectangles intersect. |
| isAssignableFrom(object, cls) | Returns true if the given object can be considered to be an instance of the class cls. This is done by testing the proto chain of the object and checking at each level to see if the proto is an instance of the given class. |
| isBoolean(s) | Returns whether or not the given value is of boolean type. |
| isDate(o) | Returns whether or not the given value is of type Date |
| isEmpty(o) | Returns whether or not the given object - which may be ArrayLike, or an object - is empty. |
| isFunction(o) | Returns whether or not the given value is of type Function |
| isNamedFunction(o) | Returns whether or not the given value is of type Function and is a named Function. |
| isNumber(n) | Returns whether or not the given value is of number type. |
| isObject(o) | Returns whether or not the given value is of type object |
| isString(s) | Returns whether or not the given value is of string type. |
| lineIntersection(l1, l2) | Compute the intersection of the two lines. |
| lineLength(p1, p2) | Calculates the length of a line between the two points. |
| lineRectangleIntersection(line, r) | Finds all points where the given line intersects the given rectangle. |
| normal(p1, p2) | Calculates the gradient of a normal to a line between the two points. |
| perpendicularLineTo(fromPoint, toPoint, length) | Calculates a line of length length that is perpendicular to the line from fromPoint to toPoint and passes through toPoint. |
| pointOnLine(fromPoint, toPoint, distance) | Calculates a point on the line from fromPoint to toPoint that is distance units along the length of the line. |
| quadrant(p1, p2) | Calculates the quadrant in which the angle between the two points lies. |
| rotatePoint(point, center, rotation) | Rotate the given point around the given center, by the given rotation (in degrees) |
| sgn(x) | Replacement for Math.sign, which IE11 does not support. |
| snapToGrid(pos, grid, thresholdX, thresholdY) | Snap the given x,y to a point on the grid defined by gridX and gridY, using the given thresholds to calculate proximity to the grid. |
| subtract(p1, p2) | Subtracts p2 from p1, returning a new point. |
| theta(p1, p2) | Calculates the angle between the two points. |
| uuid() | Generate a v4 UUID. |
