What is an html string?


JavaScript Strings

A JavaScript string stores a series of characters like "John Doe".

A string can be any text inside double or single quotes:

String indexes are zero-based:

The first character is in position 0, the second in 1, and so on.

String Properties and Methods

Normally, strings like "John Doe", cannot have methods or properties because they are not objects.
