What different between version of "ionic:1.3.0" and "ionic:driftyco/ionic-bower#1.3.0"


#1

I’m confuse about what different with below, I saw ionic-bower’s angularjs version is lower than ionic:“1.3.0”, could I just use
"ionic":“1.3.0” the good to go?

“devDependencies”: {
“ionic”: “driftyco/ionic-bower#1.3.0”
}
and
"devDependencies": {
“ionic”: “1.3.0”
}
