     question: 'What skills does a JavaScript developer need?',

       'A JavaScript developer needs to have a solid grasp of core JavaScript concepts to be successful because those will be the only common concepts that any framework or library they might depend on will use.',

       "If their focus is back-end development, concepts such as API design and integration, data modeling, server-side rendering, and database querying are a must, as these will be part of the developer's daily tasks.",
       "Front-end developers should also learn about web standards, the DOM API, web components (or lightning web components if you're working with the Salesforce ecosystem), and have some basic understanding of UX.",
       'Candidates looking to prepare for [JavaScript developer interview questions](https://roadmap.sh/questions/javascript) should include the above-mentioned topics in their study program. For that, many developers schedule their studies at their own pace through extensive documentation, online training, and roadmaps like this one to build a solid foundational knowledge base.',

       'JavaScript developers are usually paid very well due to their high demand. The web industry keeps growing, and the demand for developers who can build complex experiences is even higher. This translates to companies fighting each other over JavaScript developers, which tends to increase the base salary for these roles.',
       'That said, compensation can vary significantly based on factors such as geographical location and level of expertise. Salaries tend to be competitive in major tech hubs like New York and San Francisco, and experienced professionals or certified JavaScript developers with extensive knowledge of JavaScript frameworks often require higher pay.',

Someone who's more experienced (10+ years of experience), however, can take that number to 110,000 USD on average.",
