- Pick a framework based on any language you know of and learn it, this should be the beginning.
- After taking a week or two to learn the new framework, do a side project with it, not a serious one but something far from the basics.Try to implement some idea you've always had.
- Add the side project to your portfolio and start over again from step 1 this time with another framework which is related.
Be patient
Nothing comes easy, everything requires time and effort, so don't expect to excel at it immediately.With continuous practice and diligent effort you will notice your skills and knowledge increasing.
I wish to stress the importance of persistence here.It's what will bear the results.
