Learning Svelte (programming language)

I know very little about the Svelte programming language. This document will go over all of my knowledge of the Svelte programming language.

Hello World in Svelte

This is how you make a normal Hello World program in Svelte:

<script>
    let hw = "Hello World"
</script>

/!\ This example has not been tested yet, and may not work

Comments in Svelte

Comments in Svelte are the same as in languages like HTML.

Single line comments

Single line comments in Svelte are written like so:

<!-- This is a single line comment in Svelte !-->

Multi-line comments

Multi-line comments are the same, just more spread out. It can be written like so:

<!-- This is
a multi-line
comment in
svelte !-->

Break keyword in Svelte

Svelte does not support the break keyword.

Executing a script in Svelte

This is how you return scripts in Svelte.

<script>
    let script1 = "Test successful"
</script>
<p> {script1}!</p>

/!\ This example has not been tested yet, and may not work
