Modern JavaScript from the Beginning - Second Edition - Remove Elements

The video tutorial covers DOM manipulation methods, focusing on remove and removeChild. It provides examples of how to use these methods to remove elements from the DOM. The tutorial also explores advanced techniques for removing items using indices and demonstrates how to optimize code using arrow functions. The next section will introduce event handling.

What is the primary difference between the remove and removeChild methods?

• remove is used on the child element, removeChild on the parent element.

• remove is used on the parent element, removeChild on the child element.

• Both methods are used on the child element.

• Both methods are used on the parent element.

Which method would you use to directly remove an element with a specific ID?

• getElementById

• remove

• querySelector

• removeChild

When using removeChild, what must you first select?

• The body element

• The document

• The parent element

• The child element

How can you select a specific child element using removeChild?

• By using className

• By using getElementById

• By using nth-child

• By using querySelector

What does querySelectorAll return?

• A string

• An array

• A NodeList

• A single element

In the context of DOM manipulation, what is a NodeList?

• A list of nodes that behaves like an array

• A single node

• A JSON object

• A string representation of nodes

How can you simplify a function that removes an item using an arrow function?

• By using querySelectorAll and remove

• By using getElementById

• By using a while loop

• By using a for loop
