Which file is used to configure the compilation settings for TypeScript?

package.json
main.ts
tsconfig.json
angular.json

The correct answer is: tsconfig.json

The configuration settings for TypeScript compilation are specified within the tsconfig.json file. This file serves as the cornerstone for compiling TypeScript, allowing developers to define the compiler options, target language version, module resolution strategy, and many other settings that dictate how TypeScript code should be processed. By utilizing tsconfig.json, developers can customize aspects such as strict type checking, output directory, and include/exclude patterns for files to be compiled. This centralized configuration promotes consistency across a TypeScript project, ensuring that the compilation settings are uniformly applied, which is essential for maintaining the integrity of the codebase. The other files mentioned play different roles: package.json manages project dependencies and scripts, main.ts typically serves as the entry point for an Angular application, and angular.json contains configuration settings specifically for Angular projects, such as build and development settings but not TypeScript compilation options.
