How i can improve by skills in devopes?

Firstly, you should learn to spell developer. From there you should build on existing knowledge you have, for example, if you know some database skills, improve your existing skills by doing projects, looking at others code, reading about ways to do various things that are expected as a person with database skills. At the end of the day it is all about practice, the more you practice the better you will get - this is a general rule for everything, whether it is development, brain surgery, rocket science or javascript. Some important tips to make your learning process easier - learn to touch type, secondly learn to use sites like stackoverflow efficiently by asking the right questions, thirdly learn to write pseudocode to help you solve difficult problems, and use comments to help you describe your code to yourself and others, fourthly remember that whatever problem you are having with your code - some other developer probably had exactly the same problem before you; fithly get yourself a comfortable chair, second monitor and vertical mouse. Good luck on your development journey, and never forget that practice makes perfect.
