  ws.connect (( ) => {
  console.log('connected to client'); });

A developer has the following array of hourly wages:
Let arr = (8, 5, 9, 75, 11, 25, 7, 75, , 13, 25);
For workers making less than $10 an hour rate should be multiple by 1.25 and returned in a new array.
How should the developer implement the request?

• A.let arrl = arr-map((num) => { return ran * 1.25 }).filter((val) -> { return val < 10));
• B.let arrl = arr.filterBy((val) => val < 10 ).aapBy<(num) -> num = ..25 );
• C.let arrl = arr.filter((val) => val < 10).map((num) -> num = 1.25);
• D.let arrl = arr .rr.acArray ((val) => ( val < 10 )) ,map((num) => { num * 1.25 ));

Universal Containers recently launched its new landing page to host a crowd-funding
campaign. The page uses an external library to display some third-party ads. Once the page is
fully loaded, it creates more than 50 new HTML items placed randomly inside the DOM, like the
one in the code below:

All the elements includes the same ad-library-item class, They are hidden by default, and they are randomly displayed while the user navigates through the page.

• A.Use the DOM inspector to remove all the elements containing the class ad-library-item.
• B.Use the browser to execute a script that removes all the element containing the class ad-library-item.
• C.Use the DOM inspector to prevent the load event to be fired.
• D.Use the browser console to execute a script that prevents the load event to be fired.
