# The Console — JavaScript Fundamentals: From Syntax to Async

> Use the browser console and DevTools to print values, spot errors and experiment with code live.

## console.log

The most-used debugging tool — print any value to the DevTools console.

```js
console.log("Hello, JS!");
console.log(1 + 2);
```

Output:

```
Hello, JS!
3
```

## Other console methods

`console.error()`, `console.warn()`, and `console.table()` format output differently — useful for spotting issues fast.

## DevTools shortcut

Open DevTools with `F12` or `Ctrl+Shift+I` (Cmd+Option+I on Mac) — the Console tab doubles as a live JS REPL.
