15 mins readPython tsconfig.json and Strict Mode
In Plain English
The tsconfig.json file specifies root files and compiler options required to compile a TypeScript project. Learn the essential flags including strict, noImplicitAny, and strictNullChecks.
Core Rules to Remember
strict: true: Activates all strict mode compiler flags (noImplicitAny, strictNullChecks, etc.).
target & moduleResolution: Configures ECMAScript output standard (ES2022) and module lookup rules (NodeNext).

Micro Exercise
Inspect Compiler Options
- Declare interface TsConfig with target: string and strict: boolean.
- Create const cfg: TsConfig = { target: "ESNext", strict: true }.
- Print `${cfg.target} strict=${cfg.strict}`.
