# Variables

Variables store values in the script. They can store many types and operate mathematical operations. They are declared with the `var` keyword and modified without the keyword.

Here is an example of declaring a variable named "word" being equal to "Hello"

{% code lineNumbers="true" %}

```
var word = "Hello"
```

{% endcode %}

Here are other examples:

{% code lineNumbers="true" %}

```
var word = "Hello"
var count = 10
var active = true
```

{% endcode %}

### Types of Variables

There are many types of variables that you can use, as seen below:

<table><thead><tr><th width="133">Type</th><th width="189">Example</th><th>Description</th></tr></thead><tbody><tr><td>String</td><td><code>"Hello"</code></td><td>Text, wrapped in double quotes (<code>" "</code>)</td></tr><tr><td>Number</td><td><code>34</code>, <code>3.1416</code></td><td>Integer or decimal number. No need for extra formatting.</td></tr><tr><td>Boolean</td><td><code>true</code>, <code>false</code></td><td>True or false value. No need for extra formatting.</td></tr></tbody></table>

### Variables Reassignment

You can reassign variables by "declaring" them without the `var` keyword AFTER their initial declaration.

Example:

{% code lineNumbers="true" %}

```
-- We assing the variable x and declare its equal to 5:
var x = 5

-- We can then reassign it (x) to 10:
x = 10
```

{% endcode %}
