Example 1: convert object object to array typescript

const persons = { 
    john: { age: 23, year:2010},
    jack: { age: 22, year:2011},
    jenny: { age: 21, year:2012}
}
const resultArray = Object.keys(persons).map(index => {
    let person = persons[index];
    return person;
});

Example 2: 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

var array = new Array(); //new Array not necessary
var string;

array[0] = {key: value};
array[1] = {key1: value1};

string = JSON.stringify(array);

/*
string should look like
[{"key":"value"},{"key1":"value1"}]
*/
