In order to make more concise you can declare constructor parameters as public which automatically create properties with same names and these properties are available via this:
export class Environment {
constructor(public id:number, public name:string) {}
getProperties() {
return `${this.id} : ${this.name}`;
}
}
let serverEnv = new Environment(80, 'port');
console.log(serverEnv);
---result---
// Environment { id: 80, name: 'port' }
