compare salaries of employees and print salaries less than 5000

January 19, 2023

Hi can anyone tell how to exactly use Flat or flatMap method to flat this employee data array, so that I can get the slaries which are less than 5000, with the name of the employees.

const employeeData = [{
    name: "Suresh",
    salary: 7500
}, {
    name: "Aman",
    salary: 3400
}, {
    name: "Munish",
    salary: 10000
}, {
    name: "Chad",
    salary: 12000
}, {
    name: "Naveen",
    salary: 9500
}];

const flattendEmpdata = employeeData.flat((name, salary) => [name, employeeData[salary]]);

I was trying to use Flat and filter method in chaining method, the desired ouput will be like this

{name: Suresh, salary: 7500} , {name: Aman, salary: 3400}

>Solution :

You’re looking for the filter method. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/filter

const employeeData = [{
    name: "Suresh",
    salary: 7500
}, {
    name: "Aman",
    salary: 3400
}, {
    name: "Munish",
    salary: 10000
}, {
    name: "Chad",
    salary: 12000
}, {
    name: "Naveen",
    salary: 9500
}];

const flattendEmpdata = employeeData.filter(input => input.salary < 5000);
console.log(flattendEmpdata);
