How to check if empty string inside an object and set it into another object?

Time:11-01

I am making a re-useable drop menu component.

const objectInfo = {firstName:"", lastName:"", age:""}

const objectError = { firstNameError: false, lastNameError: false, ageError: false, }

And I am going to pass the objectError to the drop menu component to set the error to true if the related element is an empty string.

But the problem is I don't know the logic how to map through those elements and match them to the specific position.

CodePudding user response:

just loop through object keys

const objectError ={}
for(key in objectInfo){
   objectError[key] = !objectInfo[key]
}
