Ace the Angular Interview 2025 – Code Your Way to Success!

The method that allows you to select an element based on a CSS selector is `querySelector()`. This method is a part of the Document Object Model (DOM) API and is widely used in web development, including in Angular applications.

When using `querySelector()`, you can pass in a string that contains a CSS selector. This string can represent various types of selectors, including class selectors, ID selectors, attribute selectors, and more complex selectors. The method will return the first element that matches the specified CSS selector, enabling developers to interact with elements in a more intuitive way, similar to the way styles are applied in CSS.

For example, if you want to select an element with the class name "example", you can use:

```javascript

const element = document.querySelector('.example');

```

This capability makes `querySelector()` a powerful and flexible choice for manipulating the DOM, as it simplifies the process of retrieving elements without the need for more cumbersome approaches.

While the other options reflect common naming patterns, they do not correspond to any standard DOM method.
