Daily Term: Function Composition

Function Composition

Function Composition is a functional programming technique where two or more functions are combined to create a new function, such that the output of one becomes the input of the next. For example, in JavaScript, composing a function to uppercase a string and then trim it might look like compose(trim, uppercase). Function composition promotes modularity and reusability, but it can make debugging harder due to the chained execution.
