JavaScript Notes:

When using JavaScript, single or double quotation marks are acceptable and work identically to one another; choose whichever you prefer, and stay consistent
JavaScript is a case-sensitive language; firstName is NOT the same as firstname
Arrays count starting from zero NOT one; so item 1 is position [0], item 2 is position [1], and item 3 is position [2] … and so on
JavaScript variables must begin with a letter, $, or _
JavaScript variables are case sensitive (x is not the same as X)
