Strings

Most programming languages have a data type called a string, which denotes a sequence of characters, such as Hello World!. A string can contain any characters, be it a number, alphabet, or a special symbol. In most programming languages, strings are declared by enclosing the characters within single ('') or double quotation marks (""). These strings can be assigned to variables, which can then be used for further manipulation using string properties and methods.

Strings can also be defined as a sequence which are made up of many unicode characters, or in other words, they are an array of characters. Each character in a string can be accessed, and different programming languages provide different methods to perform this operation, as we'll see below.

Now let's have a closer look at strings in JavaScript.
