JavaScript 初學者 30 日計劃：每日完成一項小任務

Most beginners quit JavaScript not because it's too hard, but because the plan is too big. Here is a simple 30-day structure: one small task a day, 15–30 minutes. It assumes you already know basic HTML and CSS.

Week 1: The basics (Days 1–7)

Start in the browser console (F12). No setup needed.

console.log('Hello, JavaScript!');
console.log(25 * 4);

Then learn let and const, template literals, data types, and if/else. On Day 7, rebuild your weakest script from scratch.

Week 2: Logic and the DOM (Days 8–14)

Loops, logical operators, and querySelector. Your first page that changes:

const title = document.querySelector('h1');
title.textContent = 'I changed this with JavaScript';

Week 3: Events (Days 15–21)

Make the page react: clicks, form input, preventDefault, key presses, and event delegation.

button.addEventListener('click', function () {
  message.textContent = 'Button was clicked!';
});

Week 4: Data and APIs (Days 22–28)

localStorage, JSON.stringify/JSON.parse, and fetch.

fetch('https://api.adviceslip.com/advice')
  .then(res => res.json())
  .then(data => console.log(data.slip.advice));

Week 5: Build something (Days 29–30)

Combine everything into a small task dashboard: add, complete, and delete tasks, save them in localStorage, and load a message from an API.

Tips that make it stick

1. Set a fixed time each day. Consistency beats long sessions.
2. Type the code yourself instead of copy-pasting.
3. If you miss a day, just continue. Don't restart.
4. End each day by writing one sentence about what worked.
