Javascript:Convert Array to Object

Sample Input:

var sampleOutput= [

["name",[

["firstName","sangram"],

["midddleName","shivaji"],

["lastName","Desai"]

]

],

["address",[

["street","Naradawe Road"],

["line1","near railway station"],

["line2","behind annapurna hotel"],

["city","kankavali"],

["pin","416602"]

]

]

]

Sample Output:

var sampleInput={

name: {

firstName: "sangram",

midddleName: "shivaji",

lastName: "Desai",

},

address: {

street: "Naradawe Road",

line1: "near railway station",

line2: "behind annapurna hotel",

city: "kankavali",

pin: "416602",

},

};

Solution:

const person = [

[

"name",

[

["firstName", "sangram"],

["midddleName", "shivaji"],

["lastName", "Desai"],

],

],

[

"address",

[

["street", "Naradawe Road"],

["line1", "near railway station"],

["line2", "behind annapurna hotel"],

["city", "kankavali"],

["pin", "416602"],

],

],

];

function convertArrayToObject(person) {

let resultObject = {};

for (let element of person) {

if (Array.isArray(element[1])) {

resultObject[element[0]] = convertArrayToObject(element[1]);

} else {

resultObject[element[0]] = element[1]

}

}

return resultObject;

}

//find result & print

let resultObject = convertArrayToObject(person);

console.log(resultObject);

Output:

{

name: { firstName: 'sangram', midddleName: 'shivaji', lastName: 'Desai' },

address: {

street: 'Naradawe Road',

line1: 'near railway station',

line2: 'behind annapurna hotel',

city: 'kankavali',

pin: '416602'

}
