--description--
你可以使用循环多次执行相同的代码。
我们将学习的第一种类型的循环称为 "while
" 循环,因为它规定,当 "while" 条件为真,循环才会执行,反之不执行。
var ourArray = [];
var i = 0;
while(i < 5) {
ourArray.push(i);
i++;
}
在上面的代码里,while
循环执行 5 次把 0 到 4 的数字添加到 ourArray
数组里。
让我们通过 while 循环将值添加到数组中。
--instructions--
通过一个while
循环,把从 0 到 4 的值添加到myArray
中。
--hints--
你应该使用while
循环。
assert(code.match(/while/g));
myArray
应该等于[0,1,2,3,4]
。
assert.deepEqual(myArray, [0, 1, 2, 3, 4]);
--seed--
--after-user-code--
if(typeof myArray !== "undefined"){(function(){return myArray;})();}
--seed-contents--
// Setup
var myArray = [];
// Only change code below this line
--solutions--
var myArray = [];
var i = 5;
while(i >= 0) {
myArray.push(i);
i--;
}
