I have found the below definition about the difference
Typically, you don't use ngBind directly, but instead you use the double curly markup like {{ expression }} which is similar but less verbose.
It is preferable to use ngBind instead of {{ expression }} if a template is momentarily displayed by the browser in its raw state before AngularJS compiles it. Since ngBind is an element attribute, it makes the bindings invisible to the user while the page is loading.
but i didn't get this properly.
Can anyone explain in simple language with Example?
Thanks
