JavaScript Generators
JavaScript Generators are a special type of function that can be paused and resumed, allowing for the production of a sequence of values over time. They use the `function*` syntax and the `yield` keyword to return values and control execution flow. Generators are particularly useful for handling asynchronous operations, iterating over large datasets, and implementing custom iterators.
Developers should learn JavaScript Generators when dealing with complex asynchronous code, as they simplify handling of promises and async/await patterns, making code more readable and maintainable. They are also essential for creating lazy evaluation sequences, such as infinite data streams or memory-efficient iterations over large collections, and are commonly used in libraries like Redux-Saga for state management in React applications.
