WebIn this example we use Proxy to toggle an attribute of two different elements: so when we set the attribute on one element, the attribute is unset on the other one..

Classes Summary: in this tutorial, you will learn about JavaScript getters and setters and how to use them effectively. A function in JavaScript is similar to a procedurea set of statements that performs a task or calculates a value, but for a procedure to qualify as a function, it should take some input and return an output where there is some obvious relationship between the input and the output.
