Modern Front end Complexity: essential or accidental?

Modern frontend development has evolved from simple HTML/CSS/JavaScript into a complex ecosystem requiring multiple transpilation layers, build tools, and dependencies—a complexity that may be partially unnecessary given current browser capabilities. This growing gap between source code and browser runtime creates significant technical debt, vendor lock-in risks, and increased maintenance burden for IT organizations managing web application portfolios. CIOs should evaluate whether current frontend architecture choices deliver proportional business value or represent accumulated technical complexity that could be simplified through emerging standards and native browser capabilities.
