Hello world, tadi style

Here’s how to code all the classic ‘hello world’ examples using a slippy mindset.

Hello world

Easy, just an html file with the following words.

Hello world!

Hello world!

Button counter

Another classic. A button that counts upwards.

<button onclick="handleClick()">Count: <span id="count">0</span></button>

<script>
  const span = document.querySelector("#count");
  const handleClick = () => {
    span.textContent = parseInt(span.textContent) + 1;
  };
</script>

To-do list

We can use templates for this one.

<main></main>
<button onclick="addItem()">Add item</button>

<template>
  <p style="display: flex; gap: 11px">
    <input type="checkbox" />
    <input type="text" />
    <button>Delete</button>
  </p>
</template>

<script>
  const main = document.querySelector("main");
  const template = document.querySelector("template");

  const addItem = () => {
    const fragment = template.content.cloneNode(true);
    const item = fragment.querySelector("p");
    const button = item.querySelector("button");
    button.addEventListener("click", () => item.remove());
    main.append(item);
  };
</script>

Any others?

Do you know any other classic examples I could make? Let me know. My details are on todepond dot com.
