I think to join ScholarHat is my one of the best decision of my career because before joining ScholarHat I was aware that java-script eating other technologies but I had moderate knowledge about the JS and JQUERY like other most of the developers but now I'm a confident full-stack javascript developer using MEAN STACK because of ScholarHat. So It plays a huge role in my career to enhance my skills in javascript technologies from zero to Hero. The credit goes to the team/person who designs the syllabus of MERN stack training which step by step covers almost all the useful concepts used in real-life development. I got everything that I was looking to enhance my skills, Specially ScholarHat is a unique source of learning about trending technologies like ReactJS and Node.js, I think ScholarHat is the only Organization in Delhi-NCR which gives quality training at a reasonable price.

Training is all about covering all the topics, which I was looking for, definitely I got what I wanted. The explanation of each n every topic was too clear, that was done only on through the Trainer. Designing of syllabus of MERN full stack Development is tremendous, everything is step by step and covers almost all the concepts using in real-life development. I understand, that the training also requires audiences to self-learn, lot of interaction is needed by Candidates.
