String manipulation is a fundamental aspect of programming in JavaScript.
One common task is capitalizing the first letter of a string. Whether you’re formatting user input or displaying dynamic content, knowing how to manipulate strings effectively is essential.
```javascript
function capitalizeFirstLetter(str) {
return str.charAt(0).toUpperCase() + str.slice(1);
}
// Example usage:
const originalString = "hello world";
const capitalizedString = capitalizeFirstLetter(originalString);
console.log(capitalizedString); // Output: "Hello world"
```
