Difference between global & globalThis

Let's get straight to the point. global and globalThis both refer to JavaScript's global object , but they differ in scope and compatibility across environments. What is global?? global is NodeJS-specific and serves as the top-level object containing built-in functions like console and setTimeout . It does not exist in browsers , where attempting to access it throws a ReferenceError .​ This environment-specific nature limits its use to server-side code. global is only specific to NodeJS as will give different result based on different enviroment. Browsers: window Node.js: global Web Workers: self Strict mode functions: undefined This made writing universal JavaScript code painful. Before ES2020, you needed this ugly code to get the global object: function getGlobalObjectOldWay () { // Browser if ( typeof window !== 'undefined' ) return window ; // NodeJS if ( typeof global !== 'undefined' ) return global ; // Web Worker if ( typeof self !== 'undefined' ) return self ; // Fallback retur
