Intrinsic event attributes, such as "onclick," pose limitations when trying to invoke specific functions. In an instance where a "clear()" function is called from an "onclick" attribute, the invocation may fail. This issue arises due to how intrinsic event attributes internally implement their behavior.
Upon scrutinizing the code, it becomes apparent that the "clear()" function is positioned as a global function within the script block. However, when attempting to invoke it through the "onclick" attribute, the result is the invocation of "document.clear()" instead. This occurs because intrinsic event attributes inherently operate within a scope that encompasses their surrounding elements.
To rectify this issue, one could consider renaming the "clear()" function to something unique, thereby avoiding potential conflicts. Alternatively, explicitly calling "window.clear()" would also resolve the problem.
Nevertheless, the most recommended solution for event handling in modern web development involves leveraging the "addEventListener" method, which offers greater control and flexibility. By binding event handlers using "addEventListener," the confusion and compatibility issues associated with intrinsic event attributes can be circumvented altogether.
