Frontend Architect Curriculum

Modern JavaScript & TypeScript

Deconstruct closures, execution contexts, generic constraints, mapped utility types, and structural type narrowings.

Syllabus Modules

Module 2.1: Scopes, Closures and ESM modulesModule

Understand scoping contexts, JIT execution phases, closures, and ESModules bundling structures.

Module 2.2: Generics & Strict BoundariesModule

Build robust API integration guards utilizing generic constraints and discriminated unions.

Detailed Topics & Submodules

Modern JS: ES6+, Closures & Scope

Master advanced scopes, execution contexts, lexical closures, prototypal inheritance, and ESModules.

Why It Matters: Advanced closures and modular scopes form the bedrock of reusable framework APIs.
Skills:Lexical scope bindingsPrototype chainsESModule compilation rules

TypeScript Generics & Utility Types

Build robust, type-safe API boundaries utilizing generics, mapped types, and strict type assertion guards.

Why It Matters: Strict compilation boundaries eliminate runtime errors when matching data across backend APIs.
Skills:Generic interface constraintsDiscriminated unions narrowingCustom type guard functions
