Exploring ES New Features and Compatibility with the Kangax Compatibility Table
This article introduces the Kangax ES compatibility table, showing how to view new ECMAScript features, their support across browsers and Node.js, and explains the table’s layout, version selectors, and color‑coded compatibility indicators for developers seeking up‑to‑date feature information.
Originally I wanted to write a detailed article about the new features of ECMAScript (ES), but I decided to keep it brief.
ES new features, browsers, and Node.js are constantly evolving; how can we keep track of which features exist and their compatibility? The answer is a single website:
https://kangax.github.io/compat-table/es2016plus/
Opening this remarkable site, you will see a table where you can tick options such as 5, 6, 2016+, next, etc., which correspond to different ES standards (the example shows the ES2016+ standard).
The leftmost column "Feature name" lists the specific ES features for the selected standard, such as Object.fromEntries , optional catch binding, and many others.
The table is divided into sections: "Compilers/polyfills" records compatibility of various compiler versions like Babel, "Desktop browsers" shows browser support, and "Servers/runtimes" displays compatibility for runtimes such as Node.js.
For example, the Node.js compatibility section shows each Node.js version as a column and each ES feature as a row; green means full support, yellow indicates partial support, and red means no support.
That’s the whole article—feel free to unfollow now.
