Below is the JSON data:
let JSON_RESPONSE = `{"birthDates": ["2017-01-02","2016-07-15"]}`
There is a TypeScript object called Children with an array of Date objects and an ES6 constructor:
class Children {
birthDates: Date[] = []
constructor(values: Object = {}) {
Object.assign(this, values)
}
}
The goal is to initialize this object using the JSON data to convert the dates:
const children = new Children(JSON.parse(this.JSON_RESPONSE))
children.birthDates.forEach(it => {
console.log(it.getDate())
})
However, since Children#birthDates are stored as Object types instead of Date, explicit new Date() initialization is needed:
children.birthDates.forEach(it => {
console.log(new Date(it).getDate())
})
The question remains on how to convert JSON data to valid Date objects within the constructor without manual property mapping.
It seems that Object.assign is not suitable for deep type inheritance as it only performs a shallow copy.
