AngularJS
AngularJS is an open source front-end JavaScript framework. AngularJS extends HTML to develop rich and powerful front-ends. It reduces the repetitive use of HTML code. This repetition can be avoided by using the directives provided by AngularJS which saves much time and effort.
AngularJS Expressions
- Expressions can be written inside double braces:
{{ expression }}
- Expressions can also be written inside a directive:
ng-bind="expression"
- AngularJS will resolve the expression, and return the result exactly where the expression is written
- Expressions are much like JavaScript expressions: They can contain literals, operators, and variables.
Example:
{{ 5 + 5 }} or {{ firstName + " " + lastName }}
