Functions should make it clear (with naming and documentation) when they will modify input arguments and avoid modifying arguments otherwise. Creating copies of collections and ...

All functions in JavaScript are first class, meaning that you can use them anywhere you would use a value, so it’s possible to create a first-class function that is not also a lambda. You can pass any function as data, but when we talk about lambdas in JavaScript, we’re talking abo...
Skew functions are a little different from scaling and rotation functions in that they apply a distortion effect relative to a single point. The amount of distortion is proportionate to the angle and distance declared, meaning that the further the effect continues in a direction the more pronounced...
