What is the difference between delete and remove?

Remove and Delete are defined quite similarly, but the main difference between them is that delete means erase (i.e. rendered nonexistent or nonrecoverable), while remove denotes take away and set aside (but kept in existence).

How do you remove an element from a DOM?

If you want to remove the element from the DOM entirely, you can use the removeChild() method. var elem = document. querySelector('#some-element'); elem. parentNode.

How do you remove an element based on value?

If you are identifying the element to be removed by its value, you can delete the element from its index after identifying the index with the indexOf() method. If you want to use the value of the element you are removing, then use the filter() method, or a combination of the indexOf() and splice() methods.
