How to filter and checked matches conditionally with multiple fields passing in string; i have a request as like below:

{
name: "abc",
email: "",
phone: "123456",
match: "phone"
}

In that case i have to filtered array and get match phone objects in response and i have an array as like below

[{name: "abc", email: "[email protected]",phone:"123456"}, {name: "abc", email: "[email protected]", phone:"1236"}, {name: "pqr", email: "[email protected]", phone:"123456"} ]

in that case my expected output as like below

[{name: "abc", email: "[email protected]",phone:"123456"}, {name: "pqr", email: "[email protected]", phone:"123456"} ]

Note: my filter condition would be change as per the match string it could be on

1st request type
{
email: "[email protected]",
phone: "123456",
match: "phone,email"
}

Result:
[{name: "pqr", email: "[email protected]", phone:"123456"}]

2nd request type
{
name: "abc",
email: "[email protected]",
phone: "1236",
match: "phone,email"
}

Result:
[ {name: "abc", email: "[email protected]", phone:"1236"}]

name,phone or phone or email or name,email,phone or name only

in that case i have to manipulate filter based on match string

Even though I don't understand 100% of your question, I believe that the code below can help you.

const data = [
  {name: "abc", email: "[email protected]",phone:"123456"}, 
  {name: "abc", email: "[email protected]", phone:"1236"}, 
  {name: "pqr", email: "[email protected]", phone:"123456"} 
]

const options = {
  name: "abc",
  email: "",
  phone: "123456",
  match: "phone"
}

function filter(data,options){
    const keys = options.match.split(',')
    return data
    .filter(item=>{
        return keys
        .map(key=>item[key] === options[key])
        .every(check => check)
    })
}

const test = filter(data,options)

console.log(test)

You can define a function, filterArr(arr, cond) that can be used to test every condition on the fields specified by condition.match property as follows:

const
      input = [{name: "abc", email: "[email protected]",phone:"123456"}, {name: "abc", email: "[email protected]", phone:"1236"}, {name: "pqr", email: "[email protected]", phone:"123456"} ],
      
      cond1 = {name: "abc", email: "", phone: "123456", match: "phone"},
      
      cond2 = {email: "[email protected]", phone: "123456", match: "phone,email"},
      
      filterArr = (arr, cond) => arr.filter(item => cond.match.split(',').every(c => cond[c] === item[c])),
      
      output1 = filterArr(input,cond1),
      
      output2 = filterArr(input,cond2);
      
console.log( output1 );
console.log( output2 );
