Angular expression does not evaluate



Hi to everyone,

I hope I am hitting the right group.

I am beginner in JavaScript and AngularJS and even NodeJS. I have following problem. I generated basic NodeJS workspace and I wanted to see how AngularJS exprssions work. So I added simple line: “


” somewhere after ng-app directive, and nothing happend. The expression does not evaluate! Page renders “{{1+2}}” instead of “3”!?
