Strings are wrapped in quotations. They are words or sentences in javascript.
Strings are indexed
Each string has indexed all of the characters. Consider the word “chicken”:

Javascript indexes it starting at zero. Calling a character outside the string length will return undefined.
String methods
Built-in methods to strings.
Determining length of string
You can have returned the length of a string by using string.length like so:
let S = "string";
console.log(S.length); Examples
There are plenty of examples on MDN. Some methods are:
- searching within a string
- replacing part of a string
- Turn all characters to upper case
String methods with arguments
Arguments are inputs to pass into the method to change how it performs. For example, indexof which you pass where characters are within a string.
String template literals
Can be used to replace variables with their values in a string for example:
`I counted ${3 + 4} sheep` You use backticks instead of quotations.
