The three-number part clicked pretty fast since you just chain the helper twice.
Start by implementing the curried function using nested arrow functions that leverage the provided addTwoNumbers helper. Then, discuss generalization to N numbers by proposing a recursive curried function that accumulates arguments until a termination condition, or by using a fixed-arity approach with a utility like curry. Emphasize clarity, reusability, and trade-offs between different implementations.
Pro tip: Mention that while recursion is elegant, it may lead to stack overflow for very large N; an iterative approach or using Function.length to determine arity can be more robust. Also, highlight that currying enables partial application, which is valuable in functional programming and event handling.
Write the curried function using nested arrow functions: const addThreeNumbers = a => b => c => addTwoNumbers(addTwoNumbers(a, b), c);. Ensure it correctly uses the helper.
Briefly define currying and how it transforms a function with multiple arguments into a sequence of unary functions. Mention its benefits like partial application and composability.
Propose a recursive curried function that collects arguments until a specified arity is reached, then applies the reduction. Alternatively, suggest using a curry utility that supports variadic functions.
Compare recursive vs. iterative approaches, consider performance and stack limitations, and address how to handle zero or one argument. Mention the importance of clear termination conditions.
Conclude by emphasizing how currying aids in creating reusable, composable functions, and relate it to scenarios like configuring API calls or event handlers in Salesforce development.
