--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;
