As a JavaScript person, you will probably want to start using JavaScript frontend frameworks like React/Next.js, Vue/Nuxt.js, Astro, etc. These frameworks allow you to build very fast websites, without page reload.
You can connect these frontend frameworks with a Headless CMS which is, ideally, open-source and written in JavaScript/TypeScript too. This way, you can customize both the frontend and the CMS using the same programming language.
We created Strapi, the most popular open-source Headless CMS, to replace legacy stacks with full JS stacks: from the frontend framework to the CMS.
