How to simulate a for loop in Svelte templates

New Course Coming Soon:

Get Really Good at Git

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

<script>
let goodDogs = ['Roger', 'Syd']
</script>

{#each goodDogs as goodDog}
	<li>{goodDog}</li>
{/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.

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:

{#each Array(rows) as _, row}
  {row}
{/each}
Are you intimidated by Git? Can’t figure out merge vs rebase? Are you afraid of screwing up something any time you have to do something in Git? Do you rely on ChatGPT or random people’s answer on StackOverflow to fix your problems? Your coworkers are tired of explaining Git to you all the time? Git is something we all need to use, but few of us really master it. I created this course to improve your Git (and GitHub) knowledge at a radical level. A course that helps you feel less frustrated with Git. Launching Summer 2024. Join the waiting list!
