Enumerate properties on an object
You have two options, using the Object.keys() and then forEach, or use for/in:
class stationGuide { station1: any; station2: any; station3: any; constructor(){ this.station1 = null; this.station2 = null; this.station3 = null; }}let a = new stationGuide();Object.keys(a).forEach(key => console.log(key));for (let key in a) { console.log(key);}
With the Reflect object you are able to to access and modify any object programmatically. This approach also doesn't throw a "Element implicitly has an 'any' type because expression of type 'string' can't be used to index type '{}'" error.
class Cat { name: string age: number constructor(name: string, age: number){ this.name = name this.age = age }}function printObject(obj: any):void{ const keys = Object.keys(obj) const values = keys.map(key => `${key}: ${Reflect.get(obj,key)}`) console.log(values)}const cat = new Cat("Fluffy", 5)const dog = { name: "Charlie", age: 12, weight: 20}printObject(cat)printObject(dog)
