In most programming languages strings are the wild card data type that can be used to hold information and values that don’t fit inside of any other data types. This means that virtually any letter, number, or symbol can be stored in a string. However, when using strings to store information, think about how that information will be used. For example, if you’re storing data that will later be processed by a browser, think about the way the browser will interpret symbols like “&” and “<” which may not render correctly when rendered by the browser’s HTML engine.
