Let’s say the following is our object −
var employee = [ { name: "John", amount: 800 }, { name: "David", amount: 500 }, { name: "Bob", amount: 450 } ]
We need to multiple the “amount” value with 2, only if the amount is greater than 500 i.e. the expected output should be −
[ { name: 'John', amount: 1600 }, { name: 'David', amount: 500 }, { name: 'Bob', amount: 900 } ]
Example
Here is the sample example for multiplying the object values −
var employee = [ { name: "John", amount: 800 }, { name: "David", amount: 500 }, { name: "Bob", amount: 450 } ] console.log("Before multiplying the result=") console.log(employee) for (var index = 0; index < employee.length; index++) { if (employee[index].amount > 500) { employee[index].amount = employee[index].amount * 2; } } console.log("After multiplying the result=") console.log(employee)
To run the above program, you need to use the following command −
node fileName.js.
Here, my file name is demo257.js.
Output
This will produce the following output on console −
PS C:\Users\Amit\javascript-code> node demo257.js Before multiplying the result= [ { name: 'John', amount: 800 }, { name: 'David', amount: 500 }, { name: 'Bob', amount: 450 } ] After multiplying the result= [ { name: 'John', amount: 1600 }, { name: 'David', amount: 500 }, { name: 'Bob', amount: 900 } ]
