Assigning values to a computed property in JavaScript?
Following is our object −
const customerDetails=[ {customerFirstName: "David"}, {customerLastName: "Miller"}, {customerCountryName: "US"}, {customerAge: "29"}, {isMarried: false}, {customerCollegeName: null} ];
Let’s assign values to a computed property using slice() along with map().
Example
const customerDetails=[ {customerFirstName: "David"}, {customerLastName: "Miller"}, {customerCountryName: "US"}, {customerAge: "29"}, {isMarried: false}, {customerCollegeName: null} ]; const newCustomerDetails = customerDetails.slice(2,4).concat(customerDetails[5]).map(obj=>({ propertyKey: Object.keys(obj)[0], propertyValue: Object.values(obj)[0] })); console.log(newCustomerDetails);
To run the above program, you need to use the following command −
node fileName.js.
Here, my file name is demo135.js.
Output
This will produce the following output −
PS C:\Users\Amit\JavaScript-code> node demo135.js [ { propertyKey: 'customerCountryName', propertyValue: 'US' }, { propertyKey: 'customerAge', propertyValue: '29' }, { propertyKey: 'customerCollegeName', propertyValue: null } ]
