You can first merge both arrays,
Then use Array.prototype.reduce() to make an object for each key and finally use Object.values to achieve the output you want.

const arr1 = [
  {name: "Mobile", quantity: 18472.8},
  {name: "Laptop", quantity: 20117.535000000003},
  {name: "Tablet", quantity: 2609.75},
  {name: "Watch", quantity:6205}
]

const arr2 = [
  {name: "Mobile", quantity: 26290.65},
  {name: "Laptop", quantity: 11844.774},
  {name: "Tablet", quantity: 416.8}
]

const res = Object.values([...arr1, ...arr2].reduce((acc, curr) => {
   if(!acc[curr.name]) {
     acc[curr.name] = curr;
   } else {
     acc[curr.name].quantity += curr.quantity;
   }
    
   return acc;
   
}, {}));

console.log(res)
