Usage
The Same Way

No one understands me as she does.
Tip!
Remember that in this context, using 'like' will make your sentences informal and we advise you to use 'as' instead in formal contexts.
Comparison
'Like' is used to compare two things. For instance, we want to compare two students and show that they both have issues with a specific course. Watch:
Harry, like Tom, has difficulty with learning Maths.
Note that we cannot use 'as' in this context.
The Role of
We use 'as' to show that someone or something plays a specific role. This can be expressing a job. Have a look:
He works as a caretaker.
Note that if we use 'like,' it would express a different meaning. 'Like' would suggest that someone or something has a similar role to another.
