What does the following JavaScript code do?let titles = "Mr.|Mrs.|Miss|Ms.|Dr.";let spotTitle = new RegExp(titles, "g"); a. creates a text string and stores it in the variablespotTitle b. defines a regular expression with a global flag by creating an object constructor c. defines a function to search for the substrings"Mr.","Mrs.","Miss","Ms.", and"Dr." d. throws an error because it attempts to enclose a regular expression in quotation marks instead of forward slashes B. Which of the following regular expressions will match both the substring "cat" (part of the word “catering”) and the substring "Cat" in the string "For your catering needs, call Cat!"? a. /cat/ig b. /cat/g c. /cat/ d. / cat /Create a Vector2D class with properties x and y and a proper constructor method. Plus, minus and multiplication with a scalar operators should be overloaded. Create a Body class with properties of pos, vel, mass and constructor(float Mass, Vector2D Pos, Vector2D Vel), addForce(Vector2D F) and Move(float dt) methods. Your program should create an array or collection of Bodies, at each time step (dt), calculate forces that bodies exert each other and apply accordingly. Finally, in a 2D space, bodies should move freely based on their properties and applied forces. You can use option buttons or another element to represent bodies and move them inside the form.
