you can use reduce

var myCars=[{ "name": "Axio", "priceLakh":22.5 }, { "name": "Axio0", "priceLakh":22.5 }, { "name": "Axio00", "priceLakh":22.5 }, { "name": "Axio000", "priceLakh":22.5 },]

const sum = myCars.reduce((res, {priceLakh}) => res + priceLakh, 0 )

console.log(sum)

You can use forEach loop to calculate the sum.

var myCars=[{ "name": "Axio", "priceLakh":22.5 }, { "name": "Axio0", "priceLakh":22.5 }, { "name": "Axio00", "priceLakh":22.5 }, { "name": "Axio000", "priceLakh":22.5 }],sum=0;

myCars.forEach(element => {sum=sum+element.priceLakh;});

console.log("₹"+sum+" Lakhs")

Doesn't look like one line to me. – Robo Robok May 28 '22 at 08:53
It's one line only i just formatted in a proper way. – Sumit Sharma May 28 '22 at 09:28
It really is not. You're defining a variable for it and then manipulate it. It's 2 lines at best. One line means a single expression. – Robo Robok May 28 '22 at 19:59

You can use something like this. The reduce operator and destructuring feature

var myCars = [
  { name: "Axio", priceLakh: 22.5 },
  { name: "Axio0", priceLakh: 22.5 },
  { name: "Axio00", priceLakh: 22.5 },
  { name: "Axio000", priceLakh: 22.5 },
];

var answer = myCars.reduce((partialSum, {priceLakh}) => partialSum + priceLakh, 0);

console.log(answer);
