cf1111c1c11feddfaeb8bdef 通过索引修改数组中的数据 1 https://scrimba.com/c/czQM4A8 18241 modify-array-data-with-indexes

--description--

与字符串的数据不可变不同,数组的数据是可变的,并且可以自由地改变。

示例

var ourArray = [50,40,30];
ourArray[0] = 15; // equals [15,40,30]

提示
数组名称和方括号之间不应有任何空格,如array [0]尽管 JavaScript 能够正确处理,但可能会让看你代码的其他程序员感到困惑。

--instructions--

修改数组myArray中索引0上的值为45

--hints--

myArray的值应该 [45,64,99]。

assert(
  (function () {
    if (
      typeof myArray != 'undefined' &&
      myArray[0] == 45 &&
      myArray[1] == 64 &&
      myArray[2] == 99
    ) {
      return true;
    } else {
      return false;
    }
  })()
);

你应该使用正确的索引修改myArray的值。

assert(
  (function () {
    if (code.match(/myArray\[0\]\s*=\s*/g)) {
      return true;
    } else {
      return false;
    }
  })()
);

--seed--

--after-user-code--

if(typeof myArray !== "undefined"){(function(){return myArray;})();}

--seed-contents--

// Setup
var myArray = [18,64,99];

// Only change code below this line

--solutions--

var myArray = [18,64,99];
myArray[0] = 45;
