如何安装svelte

Svelte templates offer us the fantastic each block that lets us iterate on an array, or anything that is iterable:

苗条的模板为我们提供了奇妙的每个块，使我们可以在数组或任何可迭代的对象上进行迭代：

{#each goodDogs as goodDog}	
{goodDog}
{/each}

But what if you want to repeat a block for a few times, based on a variable? Let’s say we have the rows variable that holds a number, and we want to use that as the loop variable.

但是，如果您想基于变量重复执行几次块，该怎么办？ 假设我们有保存数字的rows变量，并且我们想将其用作循环变量。

We can do what we need by creating an array, using the Array(n) syntax. This will create an array, initializing it with n items:

我们可以通过使用Array(n)语法创建一个数组来完成所需的工作。 这将创建一个数组，并使用n项目对其进行初始化：

{#each Array(rows) as _, row}  {row}{/each}
