Just in case any non-programmers are reading this, the quotes around a string (like your name in the Codecademy example in question), have nothing to do with case, or being case-sensitive. Programming languages have basic building blocks called primitive data types, and for many programming languages, strings represent one type of those building blocks. Traditionally, strings are indicated by putting double- or single-quotes around the letters of the strings, but they just as easily could be indicated by two parentheses, or dollar signs. It's a convention for denoting a string, no more, just like quotes in English and certain other natural languages represent certain features of the language, often direct speech.
