How does Angular handle multiple environments (e.g., development, production)?

• Angular uses the fileReplacements option in angular.json.
• You create environment files like environment.ts and environment.prod.ts.
• During build, Angular replaces the environment file based on the target configuration.

Example in angular.json:

"configurations": {

"production": {

"fileReplacements": [

{

"replace": "src/environments/environment.ts",

"with": "src/environments/environment.prod.ts"

}

}
}

• Allows different API endpoints, debug flags, or configurations per environment.
