Solution Review: Using Sequence in Function

Explore how to implement the sequence function within a TypeScript application to simultaneously verify multiple conditions. This lesson helps you understand the functional programming approach to managing complex requirements efficiently in your code.

We'll cover the following...

Solution

TypeScript 3.3.4
const application = (airplane: Airplane) => {
    return pipe(
        eitherSequence(
            checkEnoughCrew(airplane),
            checkEnoughFuel(airplane),
            checkNotOnFire(airplane)
        ),
        E.map((res: Airplane[]) => res[0]),
    );
};
console.log(application({crew:5,fuel:6,onFire:true}));
