How do i make my function return ture or false ?

[Deepak8717]

Hi, I am working on form validation and i have quick question but before that i would like to present my Pseudocode

const validateEmail = (emailvalue) => {
   if emai is not valid
      shows error
     else
        hide error
 }


const comparePassword =(pass, confirmPass)=>{
    if passwords do not match
       shows error
     else
       hide error
}


const validate=(value)=>{
    checks if values are empty
           shows  error
        else
              hide "field can't be empty error"
               validateEmail(email)
               confirmPassword(pass,confirmPass)
}

const submitHandle = (e)=>{
    e.preventDefault();
    if(validate(value)){
        submit the input values
        print success message
        clear the inputs
     }
}

now, validate function does the job and shows all kind of error if there are any. However I want validate function to return true or false so that i can show a success message along with submitting the values.

How I understood your query is, that you want to have a consolidated return type for all your validations.
Going by the above understanding, you can prepare your return type from the core of the stack. A simple tweak to the above logic would be

const validateEmail = (emailvalue) => {
   if emai is not valid
      shows error
      return false
     else
       hide error
       return true
 }


const comparePassword =(pass, confirmPass)=>{
    if passwords do not match
       shows error
      return false
     else
       hide error
       return true
}


const validate=(value)=>{
    checks if values are empty
           shows  error
            return true
        else
              hide "field can't be empty error"
              return (validateEmail(email) && confirmPassword(pass,confirmPass))
}

const submitHandle = (e)=>{
    e.preventDefault();
    if(validate(value)){
        submit the input values
        print success message
        clear the inputs
     }
}
