just as
1. At the same time as something else. Just as I was calling the police, Sophie came home, thank goodness.
2. In the same manner as someone or something else. Just as I thought—Brian forgot to pick up the cake.
3. To the same extent as someone or something else. Geez, you drive just as slow as Dad. Let's pick up the pace!
just as
1. In precisely the same way as. For example, He's signing his name just as he's always done it. [Early 1600s]
2. Also, just so. To the same degree as. For example, Jim's running just as fast as his friend, or He intended to give them just so much work as they could do in a day. [Late 1600s] Also see just so.
