  • Question 52

    A developer is required to write a function that calculates the sum of elements in an
    array but is getting undefined every time the code is executed. The developer needs to find
    what is missing in the code below.
    Const sumFunction = arr => {
    Return arr.reduce((result, current) => {
    //
    Result += current;
    //
    ), 10);
    );
    Which option makes the code work as expected?
  • Question 53

    Given the code below:
    01 function GameConsole (name) {
    02 this.name = name;
    03 }
    04
    05 GameConsole.prototype.load = function(gamename) {
    06 console.log( ` $(this.name) is loading a game : $(gamename) ...`);
    07 )
    08 function Console 16 Bit (name) {
    09 GameConsole.call(this, name) ;
    10 }
    11 Console16bit.prototype = Object.create ( GameConsole.prototype) ;
    12 //insert code here
    13 console.log( ` $(this.name) is loading a cartridge game : $(gamename) ...`);
    14 }
    15 const console16bit = new Console16bit(' SNEGeneziz ');
    16 console16bit.load(' Super Nonic 3x Force ');
    What should a developer insert at line 15 to output the following message using the
    method ?
    > SNEGeneziz is loading a cartridge game: Super Monic 3x Force . . .
  • Question 54

    A developer wrote the following code:
    01 let X = object.value;
    02
    03 try {
    04 handleObjectValue(X);
    05 } catch (error) {
    06 handleError(error);
    07 }
    The developer has a getNextValue function to execute after handleObjectValue(), but
    does not want to execute getNextValue() if an error occurs.
    How can the developer change the code to ensure this behavior?
