I NEED CORRECTION IN EXERCISE 1 STORE 1 :

OOJS: Task 1 
function Shape(name, sides, sideLength) {

  this.name = name;

  this.sides = sides;

  this.sideLength = sideLength;        

    // function that does the calculation

  this.calcPermiter =  function(){

    return console.log((this.sides)*+this.sideLength) 
}

}

// add a new instance to Shape

let square = new Shape("Square", 2,5)    
square.calcPermiter();

let triangle = new Shape("triangle", 2,3)
triangle.calcPermiter()

(no script tag I took to load the code on the site)

Hello @Hacker_Man_De_Souza

you doing great well done

just little thing
replace this

Shape.calcPermiter

also you have type here

 return console.log((this.sides)*+this.sideLength)

you write *+ which not valid

hope that help and have a nice day :slight_smile:

with this

Shape.prototype.calcPermiter

Why *+ is not valid ?

4

cause you either multiplay or add but what will *+ do ?

the only thing that close to that is *= or += which
x += y mean x = x + y
x *=y mean x = x * y

there no +*

hope that help and have a nice day :slight_smile:

Is repeating
side * 6
(this side) + (this side) + (this side) + (this side) + (this side) + (this side)

My side variable is accumulating the values ​​while my sideLength will be as many times as the side will repeat doing the perimeter calculation …

6

since the calculation of the Permiter for triangle is different than the square you need to create 2 make triangle and square subclass of shape

then write Permiter function for each one since the calculations is different

7

The program returns the 2 correct values ​​of the Triangle and Square perimeter
console.log (10) - square

console.log (6) - triangle

it worked perfectly I didn’t understand what you wanted to show me The program returns the 2 correct values ​​of the Triangle and Square perimeter
console.log (10) - square

console.log (6) - triangle

it worked perfectly I didn’t understand what you wanted to show me

8

How would you do it?

sorry it’s my bad i reread the questions and you are right

it the sides f the triangle are equal that why you do not need to do that
just multiplay the number of sides by the side length

sorry for my miss understand
