MERN Stack vs Full Stack
| MERN stack programmers cover the full web development cycle from front-end development to back-end development using JavaScript. | Full stack programmers each time get the power to switch between the front-end and the back-end development based on the needs of the project. |
| MERN stack supports model view controller (MVC) architecture to make the development process flow smoothly. | The significant advantage of enrolling a full stack coder is people are not only tied to a web development but can also look at the entire design structure. |
In MERN stack with only JavaScript developers only need to be proficient in JavaScript and JSON. | Recruiting a specialized front-end developer and a separate back-end developer will increase the cost but full stack development company can work on the both side |
| A professional MERN stack developer is the combination of four technologies: mongo dB, express, react, node.js. | Professional full stack development agency is able to take the ownership of complete design and implement the process on the site. |
A MERN stack programmer follow with a pre-built extensive suite of technologies tools. | Full stack programmers are able to get up to the data with the new technologies and tools faster than someone particularize only in front-end or back technologies. |
