typescript object from array code example
Example 1: typescript object to array
var resultArray = Object.keys(persons).map(function(personNamedIndex){
let person = persons[personNamedIndex];
// do something with person
return person;
});
// you have resultArray having iterated objects
Example 2: typescript array of objects
//Define an interface to standardize and reuse your object
interface Product {
name: string;
price: number;
description: string;
}
let pen: Product = {
name: "Pen",
price: 1.43,
description: "Userful for writing"
}
let products: Product[] = [];
products.push(pen);
//...do other products.push(_) to add more objects...
console.log(products);
/* -->
*[
* {
* name: "Pen",
* price: 1.43,
* description: "Userful for writing"
* },
* ...other objects...
*]
Example 3: typescript array
let list: number[] = [1, 2, 3];
