The evolution of JavaScript tooling and the sunset of IE 11 have shifted how developers approach ES5 legacy support, allowing for more modern code usage.
Library authors have historically needed to play it safe by transpiling back to ES5 due to their lack of control over deployment contexts, which restricted innovation.
Despite advancements, it remains crucial for both website developers and library authors to understand current ES5 usage trends while providing actionable recommendations rooted in data.
The discontinuation of support for Internet Explorer 11 liberated developers from the constraints of ES5 compatibility, enabling a greater focus on leveraging modern features of JavaScript.
