6 cutting-edge JavaScript features you can use today

JavaScript continues to evolve rapidly with the introduction of new features like BigInt, the nullish coalescing operator, Promise.any(), Promise.allSettled(), the optional chaining operator, and globalThis, all of which enhance coding efficiency and reliability. BigInt supports the representation of large integers without resorting to third-party libraries, while the nullish coalescing operator offers a more precise way to handle default values by checking for null or undefined rather than all falsy values. Promise.any() and Promise.allSettled() provide more nuanced control over asynchronous operations, allowing for more flexible promise management. The optional chaining operator simplifies the process of accessing nested properties by preventing errors when intermediate properties are undefined, and globalThis offers a consistent approach to accessing the global object across different environments. These advancements highlight the importance for developers to continually update their skills to leverage these new capabilities effectively.
