Question

I have this function that validate my form field

export default value => {
  let errors = {}
  if (!value.name) {
    errors.name = 'username is required'
  }
  return errors
}

How do I trim the value? above code doesn't do that. Is it a good idea to use Object.keys to iterate and trim all the property values?

this is my solution

export default value => {
value = Object.entries(value).reduce(
    (null, [key, value]) => ({ [key]: value.trim() }),
    {}
  )
      let errors = {}
      if (!value.name) {
        errors.name = 'username is required'
      }
      return errors
    }

Answer 1

yes you can use Object.keys

    export default value => {
    Object.keys(value).forEach(val => {
     value[val] = value[val].trim();
    })
  let errors = {}
  if (!value.name) {
    errors.name = 'username is required'
  }
  return errors
}

Answer 2

Triming object means what your question is not clear. I think your function does job of validation with form data.

 var profile = { 'first_name': 'revansiddh', 'last_name': '', 'address': 'Solpaur', 'pincode': '413224' } function validate(obj = {}) { var error = {} Object.keys(obj).forEach((m) => { if (obj[m] == '') { error = { ...error, [m]: m + 'requireed' } } }) return error } console.log("form validation", validate(profile))

Is it what you want achieve ?
