Here, I have to create a function which has 2 parameters, array of employee and attribute which returns all employees sorted based on the employees attribute being passed as second parameter.

function compare(arr, name){
    
}
let arr = [ 
    {name :"om", age:45},
    {name :"guru", age:95},
    {name :"subh", age:25},                       
    {name :"rahul", age:22},
    {name :"raju", age:35},                        
    ];

 //// output should be array either sorted by name or age

The javascript built-in array sort() function has an parameter to pass in your own compare function. The sort() function will compare 2 different values in the array and determine the position of them based on a call to the compare function with 2 parameters: a and b. By passing in a compare function, you can specify exactly what properties of the objects you want to compare. In your case, what you could use is

function compare(arr, name){
    return arr.sort((a, b) => a[name] - b[name]);
}
let arr = [ 
    {name :"om", age:45},
    {name :"guru", age:95},
    {name :"subh", age:25},                       
    {name :"rahul", age:22},
    {name :"raju", age:35},                        
    ];

You could take a function which works for numbers as well as for strings.

function sort(array, key) {
    return array.sort((a, b) => (a[key] > b[key]) - (a[key] < b[key]));
}

const
    data = [{ name: "om", age: 45 }, { name: "guru", age: 95 }, { name: "subh", age: 25 }, { name: "rahul",  age: 22 }, { name: "raju", age: 35 }];

console.log(sort(data, 'name'));
console.log(sort(data, 'age'));
