Building blocks

[hellocan]

Requirements
The constructor should take an array as an argument, this will contain 3 integers of the form [width, length, height] from which the Block should be created.

Examples
let b = new Block([2,4,6]) -> creates a Block object with a width of 2 a length of 4 and a height of 6

b.getWidth() // -> 2

b.getLength() // -> 4

b.getHeight() // -> 6

b.getVolume() // -> 48

b.getSurfaceArea() // -> 88

Your Test Cases:
let block = new Block([2,4,6]);
Test.assertEquals(block.getWidth(), 2)
Test.assertEquals(block.getLength(), 4)
Test.assertEquals(block.getHeight(), 6)
Test.assertEquals(block.getVolume(), 48)
Test.assertEquals(block.getSurfaceArea(), 88)

class Block{
  constructor(data) {
   this.data = data
  }
  getWidth() {
      return this.data[0]
  }
  getLength() {
    return this.data[1]
  }
  getHeight() {
    return this.data[2]
  }
  getVolume() {
    return this.data[0]*this.data[1]*this.data[2]

  }
  getSurfaceArea() {
    return (this.data[0]*this.data[1] + this.data[0]*this.data[2] + this.data[1]*this.data[2])*2
  }
}

提交看了答案这个题目的答案大家都差不多，没有吊打的

[hellocan]

我的是把每个方法加原型方法上，不懂错在哪了

[Go7hic]

他这个题目是用 es6 的语法 class。话说有空可以熟悉下 es6的语法，我们团队现在都是用 es6了

赞！你们团队已经站在互联网前端风口上了！那是不是需要转化es5使用尼--比如 Babel
