I Need math marks > 50 then it will show otherwise not show in given JavaScript program

Here I am not able to hide the lower mark field

let result = [];
var Avgmarks = 0,i;
let students = [{name: "Student1",sub: {math: 80,eng: 50,science: 70}},{name: "Student2",sub:{math: 40,eng: 65,science: 85}}];

students.forEach( student => {
  result.push({
    name: student.name,
    Subject: student.sub,
    marks: Object.values(student.sub).reduce((a, b) => a + b),
    
    Average:  ( Object.values(student.sub).reduce((a, b) => (a + b)) ) / ( Object.values(student.sub).length )
    
  })
});

console.log(result)

[
{
name: ‘Student1’,
Subject: { math: 80, eng: 50, science: 70 },
marks: 200,
Average: 120
},
{
name: ‘Student2’,
Subject: { math: 40, eng: 65, science: 85 },
marks: 190,
Average: 90
}
]

>Solution :

the way you are calculating average using reduce is wrong

if you know there is going to be 3 subjects always.. you can try

 { Average: Object.values(student.sub).reduce((a, b) => (a + b))/3 }

if subjects length can vary

Average:  ( Object.values(student.sub).reduce((a, b) => (a + b)) ) / ( Object.values(student.sub).length )
