The Atomic object of JavaScript is an object and which provides atomic operations such as add, sub, and, or, xor, load, store etc. as static methods, these methods are used with SharedArrayBuffer objects.This method is used to determine whether to use locks or atomic operations.SyntaxIts syntax is as followsAtomics.isLockFree(size)Example Live Demo JavaScript Example document.write(Atomics.isLockFree(7)); document.write(""); document.write(" "+Atomics.isLockFree(8)); Outputfalse false
CSS provides a property called overflow that tells the browser what to do if the box's contents are larger than the box itself. The following are the values of overflow property −ValueDescriptionVisibleAllows the content to overflow the borders of its containing element.HiddenThe content of the nested element is simply cut off at the border of the containing element and no scrollbars are visible.ScrollThe size of the containing element does not change, but the scrollbars are added to allow the user to scroll to see the content.autoThe purpose is the same as a scroll, but the scrollbar will be shown only if the ...

Operations in this method should ... Read More
