The Components Of TypeScript Compiler 🤔
Here's an overview of the various components and phases of the TypeScript compiler and compilation process:
The compiler starts by parsing the TypeScript source code(
into an Abstract Syntax Tree (AST). The AST represents the structure
and syntax of the source code in a tree-like format. During the parsing
phase, the compiler also performs syntax and lexical analysis to identify
potential syntax errors.
Next, the TypeScript compiler performs type checking based on the type annotations and inference rules. This step is crucial to catch type-related errors early in the development process. The TypeScript type checker analyzes the type information in the AST and checks if the types are being used correctly according to the language rules. If any type-related errors are detected, the compiler reports them to the developer.
Once the TypeScript code has been parsed and
type-checked, the compiler moves to the transformation phase. In this phase,
the TypeScript-specific syntax and constructs are transformed into their
interface construct is removed, and TypeScript type

After the transformation, the compiler emits the final
