Где я могу найти Исходный код Flex? [закрытый]

Я думаю, это то, что вы ищете:

let a = {
  users: {
      user1: {
          name: 'Mina',
          interested: ['programming', 'makeup', 'get an answer'],
          complexArray: [['test1'], ['test2',{
              ultimateTest: ['success', 'more success']
          }]]
      },
      user2: {
          name: 'Ernesto',
          interested: ['give an answer']
      }
  }
};

function getContent(element, address) {

    let i, j;
    let x, y, z;
    let length1, length2;
    let currentPosition = element;

    address = address.split('.');
    length1 = address.length;

    for (i = 0; i < length1; i++) {
        x = address[i].match(/\[\d\]/g);
        if (x !== null) {
            // ARRAY TYPE ADDRESS
            y = address[i].replace(/\[\d\]/g, '');
            currentPosition = currentPosition[y];
            length2 = x.length;
            for (j = 0; j < length2; j++) {
                z = x[j].replace(/\D/g, '');
                z = parseInt(z);
                currentPosition = currentPosition[z];
            }
        } else {
            // OBJECT TYPE ADDRESS
            currentPosition = currentPosition[address[i]];
        }
    }

    return (currentPosition);

}

getContent(a, 'users.user1.interested[0]'); // OUTPUT: 'programming'
getContent(a, 'users.user2.name'); // OUTPUT: 'Ernesto'
getContent(a, 'users.user1.complexArray[1][1].ultimateTest[0]'); // OUTPUT: 'success'
getContent(a, 'users.user1.complexArray[1][1].ultimateTest[1]'); // OUTPUT: 'more success'
