# Lists in Mathematica & the Wolfram Language

Lists in the Wolfram Language are a fundamental structure. They represent an ordered sequence of expressions. And since everything in Mathematica is an expression, a List is an ordered sequence of pretty much anything! For example, Lists are used to represent vectors, matrices, and tensors. They are also the standard structure for passing collections of data to functions. To become truly fluent in Mathematica, you will need to master Lists.
