A .The following JavaScript command adds a method to a built-in class that can be called on any object instance of that class. Array.prototype.scramble = function() { this.sort(function() { return 0.5 – Math.random(); }); } Select one: True False B. Suppose you have written a JavaScript for loop, and one of the statements that will execute with each iteration of the loop includes an anonymous function that uses the for loop’s counter variable, i. Which statement about this loop is true? a.The anonymous function will execute when it is called by the program, using the value ofiat the time it was encountered in the loop. b. The anonymous function will throw an error if it is called by the program after theforloop has finished iterating. c. The anonymous function will execute when it is called by the program, using the value ofiafter the final iteration of the loop. d.The forloop signals the JavaScript interpreter to copy the body of the anonymous function but not its lexical environment.

OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
Question
A .The following JavaScript command adds a method to a built-in class that can be called on any object instance of that class.

return 0.5 – Math.random();
});
}
Array.prototype.scramble = function() {
this.sort(function() {
return 0.5 – Math.random();
});
}
