globalThis | Javascript
Accessing the global property in JavaScript has always posed some difficulty. This is because
different platforms have different ways to access it.
Client-side JavaScript uses window or self
Node.js uses global
Web workers use self
The globalThis property provides a standard way of accessing the global 'this' value across environments. you can access the global object in a consistent manner without having to know which environment the code is being run in.
console.log(globalThis) //get the global this depends on your environment
The provided code snippet is using the globalThis property to access the global object ('this' value) in JavaScript. The globalThis property was introduced in ECMAScript 2020 to provide a standard way to access the global object, regardless of the environment in which the code is running. This is useful because different JavaScript environments (such as browsers, Node.js, and Web workers) traditionally used different ways to access the global object. When the code `console.log(globalThis)` is executed, it will output the global object for the current environment. The value of globalThis can vary depending on where the code is being run: - In browser environments, globalThis will refer to the global object, which is typically accessed using `window` or `self`. - In Node.js, globalThis will refer to the global object accessed using `global`. - In Web workers, globalThis will refer to the global object accessed using `self`. By using globalThis, you can access the global object in a consistent and standardized manner without needing to know the specifics of the environment in which the code is running. This provides a more portable and reliable way to access global properties in JavaScript code.
