Wider Development Knowledge
While, of course, JS is the focus, every coder must be also familiar with other skills, apps and languages related to development. For example, they should be versed in the basics of HTML and CSS.
This way, they can undertake more complex tasks, such as support for mobile devices. Experience with React, Ruby, Cake PHP, Asp.net., Node. Js. and other popular frameworks also would be an advantage, but the exact skill list mostly depends on the project.
Senior and Junior Developers and Stacks
If you need to build a project from scratch, a more senior developer is required, but if you have an already developed stack, a mid or even entry-level developer should be sufficient. If you are going to use more Junior developers, make sure they can work with your current stack, while most mid-level JS developers should be able to work with your project framework regardless of what type of stack you have.
There are many essential tools JS developers need to use: for debugging, examining the quality of nodes, diagnosing bugs, and performing QA analysis. Developers may utilise task runners, module bundlers, tools which manage asynchronous code, code linters and formatters, package managers, etc.
Assembling a Team
When building a development team, it is crucial first to make a needs assessment, where the specific requirements for a project are identified. This way, you will be able to create a dedicated team with the required expertise properly. By hiring a dedicated team, you can best harness the skill sets needed for any development project, perfectly tailored to your needs.
Hiring software developers can be challenging. The success of your project depends on many factors, including the qualifications and skills of the candidate. But with adequate preparation, it is possible to streamline the process and make the right choice.
