56bbb991ad1ed5201cd392cb 使用 push() 操作数组 1 https://scrimba.com/c/cnqmVtJ 18237 manipulate-arrays-with-push

--description--

一个简单的方法将数据添加到一个数组的末尾是通过push()函数。

.push()接受一个或多个参数,并把它“推”入到数组的末尾。

var arr = [1,2,3];
arr.push(4);
// arr is now [1,2,3,4]

--instructions--

["dog", 3]“推”入到myArray变量的末尾。

--hints--

myArray应该等于[["John", 23], ["cat", 2], ["dog", 3]]

assert(
  (function (d) {
    if (
      d[2] != undefined &&
      d[0][0] == 'John' &&
      d[0][1] === 23 &&
      d[2][0] == 'dog' &&
      d[2][1] === 3 &&
      d[2].length == 2
    ) {
      return true;
    } else {
      return false;
    }
  })(myArray)
);

--seed--

--after-user-code--

(function(z){return 'myArray = ' + JSON.stringify(z);})(myArray);

--seed-contents--

// Setup
var myArray = [["John", 23], ["cat", 2]];

// Only change code below this line

--solutions--

var myArray = [["John", 23], ["cat", 2]];
myArray.push(["dog",3]);
