# AngularJS Expressions
* * *
AngularJS uses **expressions** to bind data to HTML.
* * *
## AngularJS Expressions
AngularJS expressions are written inside double braces: **{{ expression }}**.
AngularJS expressions bind data to HTML, which is similar to the **ng-bind** directive.
AngularJS will "output" the data where the expression is written.
**AngularJS expressions** are very similar to **JavaScript expressions**: they can contain literals, operators, and variables.
Example {{ 5 + 5 }} or {{ firstName + " " + lastName }}
