Strings
You have been using strings. What are they?
In coding, a string is a piece of text - like a word or a sentence.
It is called a string because each letter or character follows on from the next. Imagine the letters hanging on a piece of string!
Usually, strings have double or single quote marks around them, like this:
"The quick brown fox"
'jumped over the lazy dog.'
