How Using Modern JavaScript May Improve Performance

Djirdeh defined modern JavaScript as JavaScript code that is written in a syntax that is supported in all modern browsers — in this context understood as the four major browsers, Chrome, Firefox, Edge, and Safari. Those browsers, together with minor browsers with the same underlying rendering engines (e.g., Opera), capture 95% of the global web traffic. Referring to Google’s research, Djirdeh posited that ES2017 is an ideal version of the JavaScript language to target when transpiling. Many ES2020 and ES2021 features still have insufficient browser support, while ES2017 strikes a better middle ground between browser support and language features. The Chrome Developer Summit is an annual conference where developers can learn about the latest tools and updates coming to the Google Chrome browser and the broader web. The 2020 edition took place online with all talks published on the summit’s YouTube channel.
