What is globalThis, and why should you start using it?

JavaScript is widely utilized across various environments, including web browsers, servers, smartphones, and robotics, each with unique methods to access the global object, making it challenging to write portable code. In browsers, the global object is accessed via `window`, `self` in Web Workers, and `global` in Node.js. The introduction of `globalThis` seeks to standardize this by providing a unified global property across all JavaScript environments, simplifying code portability. While all major browsers and Node.js versions support `globalThis`, older browsers require a polyfill, though creating a reliable polyfill is complex. The article discusses different methods of accessing the global object and emphasizes the importance of `globalThis` in ensuring code compatibility across varied environments. Additionally, LogRocket is highlighted as a tool for tracking JavaScript errors, offering insights into user experiences and facilitating error resolution.
