const result = employees.reduce((acc, emp) => { if(emp.profile === 'Senior doveloper') { let output = emp.rating1 + emp.rating2; acc = acc + output; } return acc; }, 0); console.log(result);

[@FactsByVivek123]

The solution of the assignment: Sum up the ratings of all the Senior Developer only using reduce method: const employee = [ {id:101, name: "ashish", profile: "Senior Developer", rating1:5, rating2:10}, {id:102, name: "ashok", profile: "Junior Developer", rating1:6, rating2:10}, {id:103, name: "aman", profile: "Senior Developer",rating1:7,rating2:7}, {id:104,name:"ashu",profile:"Senior Developer",rating1:8,rating2:7}, {id:105,name:"anjan",profile:"Junior Developer",rating1:9,rating2:10}, ]; const seniorCount = employee.reduce((acc, curr)=>{ if(curr.profile === "Senior Developer"){ acc += curr.rating1 + curr.rating2; } return acc; },0); console.log(seniorCount); Using map, reduce and filter method : const seniorCount = employee.filter((item)=> item.profile == "Senior Developer").map((x)=>x.rating1 + x.rating2).reduce((x,y)=>x+y,0); console.log(seniorCount);

[@harika218]

Hi, Here is my assignment let totalValue = employees.reduce((acc, emp) => { if(emp.role == "Senior Developer"){ acc += (emp.rating1 + emp.rating2)/2 } return acc; }, 0) console.log(`Reduce Operator => ${totalValue}`);

[@chanduBoddu]

const TotalRating= employes.reduce((acc, val) => { return (val.role === 'SE' && val.rating1 + val.rating2) + acc; },0); console.log("Total Rating !",TotalRating);

[@yogidunique7013]

i try with reduce method. Kindly see it. const employees = [ {id:101,name:"John", profile:"senior developer",rating1:5,rating2:10}, {id:101,name:"peter", profile:"junior developer",rating1:8,rating2:10 }, {id:101,name:"alisha", profile:"senior developer",rating1:8,rating2:7}, {id:101,name:"daniel", profile:"junior developer",rating1:7,rating2:10}, {id:101,name:"sahil", profile:"senior developer",rating1:6,rating2:10} ] const totalSum2 = employees.reduce((accumulator,data)=>data.profile==="senior developer"?accumulator+data.rating1+data.rating2:accumulator,0); console.log(totalSum2);

[@nagababuchebrolu3255]

const seniorDevelopersTotalRatingScore = employees.reduce((acc, emp) => { return acc + (emp.profile === 'Senior Developer' ? (emp.rating1 + emp.rating2) : 0); }, 0);
