Chapter XXIII · Error Handling
try
The `try` statement defines a code block to be run and monitored for runtime exceptions during execution.
01 How It Works
Think of walking across a tightrope net with a safety harness monitoring your path.
If an error occurs anywhere inside the `try` block, execution jumps immediately to the associated `catch` block.
example.js
try {
let data = JSON.parse('{"valid": true}');
console.log(data.valid);
} catch (e) {
// Handles errors if any occur
}1. Open a `try` block wrapping operational code.
2. Execute statements normally.
3. Intercept any thrown exceptions immediately.
02 Practical Example
Here is how you might see this concept applied in real-world code:
practical.js
try {
document.getElementById("missing").click();
} catch (err) {
console.log("Element not found");
}Key Takeaway
Use `try` blocks to wrap code prone to potential runtime errors.
