# Vectors

Learn how you can perform various vector operations using JAX.

## We'll cover the following

Since we are assuming you are fairly familiar with NumPy, this chapter is by no means a thorough coverage of the topic and will just serve as a quick refresher. We will practice using JAX while discovering the equivalence between normal NumPy and the JAX version of NumPy’s syntax.

Note:As a reference, we’ll use`np`

and`jnp`

respectively for default and JAX NumPy versions in our codes.

## Inner product

The inner product of two vectors can be calculated by any of the three syntaxes (** dot()**,

**and**

`inner()`

**), as shown below:**
