Now You Can Use is built for enthusiasts turned corporate engineers—developers who spent years working in enterprise backends, locked-down corporate stacks, banking portals, or legacy maintenance systems, and now want an objective, no-nonsense reference for what modern browsers support natively without polyfills, transpilers, or framework bloat.

Working on long-lived enterprise stacks freezes your mental model in whatever era you last overhauled your frontend—often an era of mandatory Babel transpilation, Sass preprocessors, defensive polyfill matrices, and a dozen utility packages just to clone an object, format a date, or position a popover. In the meantime, evergreen browser engines (Chromium, Gecko, WebKit) standardized and shipped native solutions for nearly every common layout, DOM, and runtime pain point. If your instincts still default to adding a build step or reaching for an npm dependency, this reference shows what the platform already handles natively so you can write lighter, faster, zero-bloat code.

Common requirements that historically demanded external packages or preprocessors are now standard browser features:

Rather than parsing multiple browser bug trackers or maintaining internal compatibility tables, the WebDX Community Group (Google, Apple, Microsoft, Mozilla) established Baseline to define objective, vendor-neutral readiness milestones:
