The Problems with JavaScript-based Applications

Every coin has two sides, and JavaScript-based applications are no exception from this. While they have multiple advantages, such as:

• They provide rich site interactions
• Fast website rendering after the initial page load
• They are great for interactive web applications
• You have a great selection of JavaScript frameworks and libraries you can choose from

They also come at a cost, and have their own disadvantages, such as:

• If they are not implemented correctly, SEO can get a big hit
• Initial load might require more time as often they require a heavy external library
• Proper security can be an issue if you not take care of sensitive data and trust users with their inputs
• Browser support should be taken into consideration, you may want to transpile your JavaScript down to an older version to make it work for older browsers
• JS-based applications will not work if JavaScript is disabled in the user’s browser
