🤔 AngularJS Expressions vs JavaScript
Understand the key differences between AngularJS expressions and standard JavaScript expressions.
AngularJS expressions look similar to JavaScript, but they have important differences that make them safer and easier to use within templates.
🆚 Key Differences
| Feature | AngularJS Expression | JavaScript |
|---|---|---|
| Context | Evaluated against the AngularJS $scope |
Evaluated against the window object (global) |
| Syntax | Used inside {{ }} or directives like ng-bind |
Used inside <script> blocks |
| Control Flow | No support for loops, conditionals, or exceptions | Full support (if, for, try-catch, etc.) |
| Security | Automatically prevents dangerous access (e.g. window.location) |
Full access to browser objects (can be unsafe) |
| Assignment | Cannot assign values (read-only) | Can assign and modify variables |
💡 Example Comparison
AngularJS Expression
<p>{{ 10 + 5 }}</p>
Output: 15
JavaScript
<script>
document.write(10 + 5);
</script>
Output: 15
