- Angular js expressions can be written inside double braces:{{expression}}
- It can also be written inside a directive :
ng-bind="expression"
- Angular JS will resolve the expression, and return the result exactly where the expression is written.
- AngularJS expressions are much like javascript expressions they can contains constant, variables operators an functions
eg
{{5+5}}
or
{{fname+" "+lname}}
<html>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js">
</script>
<body>
<div ng-app=" ">
<p>expression:{{5+5}}</p>
</div>
</body>
</html>
- If we remove the ng-app directive, will display thexprron as it is, without solving it.
- AngularJS will simply resolve the expression an return the result.
