+# Performance Gain Using ng-bind
+
+<br/>
+We recommend the usage of `ng-bind` in your views.
+
+It allows some performance improvements compared to the usual `{{ "{{ " }}}}` syntax, without adding too much code complexity.
+
+Your code would then look like:
+
+```
+<div ng-bing='home.myValue'></div>
+```
+
+Instead of:
+
+```
+<div>
+{{ "{{home.myValue"}}}}
+</div>
+```
