Familiarity with browser JavaScript APIs varies; some developers may overlook well-established features like document.currentScript. This API offers a reference to the currently executing <script> element, enabling straightforward property access. Despite its utility, document.currentScript is not accessible within modules, returning null instead of undefined, highlighting a design decision in its specification. Reliable support across all major browsers for over a decade means developers can use this feature confidently, representing a valuable tool for JavaScript coders willing to explore the API landscape.
