String

A String is a sequence of characters.

A string type is more complex than a number or a boolean. Along with its characters a string type contains information about its length an it lets you change any of its characters using an index. Strings can be broken into smaller strings or added on to make larger strings.

Strings can contain letters, numbers, punctuation marks, and other special characters. Strings can have characters from different languages too.

"abcdefg1234*?!"

A string variable is declared by assigning a variable to a string value:

let myString = "My nice new string is here!"

Strings have operations associated with them so that you can change them or work with parts of them.

let myString = "My nice new string is here!"
// make a smaller string
let mySmallString = myString.substr(0, myString.indexOf("g") + 1)
