What is JavaScript.
JavaScript is a high-level, interpreted programming language that’s most commonly used to make
web pages interactive and dynamic.
Here’s a simple breakdown 👇
What JavaScript Does
Adds interactivity – e.g., buttons that react when clicked, animations, games, and dynamic content.
Controls web behavior – e.g., validating forms, showing or hiding elements, loading data without refreshing the page (AJAX).
Works with HTML & CSS –
HTML structures the content.
CSS styles the content.
JavaScript makes the content interactive.
Where It Runs
In the browser (client-side): Every major browser (Chrome, Firefox, Safari, Edge) has a built-in JavaScript engine.
On servers (server-side): With Node.js, JavaScript can also run outside the browser — for backend development, APIs, and automation.
Example
Here’s a simple JavaScript example that shows a message when you click a button:
<!DOCTYPE html>
<html>
<body>
<button onclick="showMessage()">Click Me!</button>
<script>
function showMessage() {
alert("Hello, world!");
}
</script>
</body>
</html>
Key Features
Dynamic typing – You don’t need to declare variable types.
Event-driven – Reacts to user actions like clicks, scrolls, or key presses.
Prototype-based – Uses prototypes instead of classical inheritance.
Asynchronous programming – Uses callbacks, promises, and async/await for handling asynchronous tasks (like fetching data).

Depende do qual será o melhor pra você. Antes de eu começar a entrar nessa área, fui assistindo o Guanabara para aprender o básico da programção.
Eu estava em dúvida entra javascript ou python, fui de Javajavascript pelo motivo que eu já sabia programar.

「JAVAJavaScriptだな」
に変えていくことを強く主張したい

大きめのタッパーに肉じゃが用お野菜の水煮と鶏肉をぶちこみ、めんつゆをJavaJavaScriptして電子レンジでブンすゆ。鶏肉じゃが。
