State of JavaScript: TypeScript rises, Angular falls

JavaScript engineers incline toward ES6, React, and Express, while TypeScript, Vue.js, and GraphQL draw solid intrigue.

While ECMAScript 6 remains the standard for JavaScript programming, TypeScript, Microsoft's composed superset of JavaScript, may one day give ECMAScript 6 a keep running for its cash, a recently discharged report recommends.
