如果我们想重复一个字符串,我们可以使用 fill() 方法将字符串填充到数组实例中,然后将其转换为字符串 function repeatString(string, count) { return Array(count).fill(string).join(''); } 我们可以通过重复 bitbug 3 次来测试它: 使用Array 的 join() 方法 将Array 转换为字符串时,可以使用 join() 方法。
First of all, let's take a look at how many timesa specific element occursin an array. To accomplish this, we need to set thecountervariable to0, then loop through the array and increase thecounterby one each time we find the element we are looking for. When we loop through the enti...
