Syntactic Sugar II: let and where
Explore the use of let and where bindings to manage subexpressions within Haskell functions. Understand their syntax, scope differences, and how to create helper functions inside others to write clearer and more maintainable functional code. Practice by implementing helper functions to solve problems efficiently.
We'll cover the following...
Let’s continue discovering some of the syntactic sugar that Haskell offers us. In this lesson, we focus on bindings for subexpressions.
Sometimes when writing functions, the expressions on the right hand side of equations can become quite complex, especially when they involve repeated subexpressions. For example, consider the task to write a function which solves the quadratic equation
We know that this equation has solutions as long as
...
