This type allows you to form the result of custom form validation. It has a constructor. If you call it without specifying parameters, it returns an empty validation result object:

const result = new  ValidationResult();

You can pass the array of error messages (messages) and lists of errors in context fields (contextErrors and viewContextErrors) to the constructor.

const result = new  ValidationResult(
    [`All checkboxes on the form need to be checked`],  
    { 
        stringname: ['The value needs to be at least 10 characters  long'], 
        stringname_2: ['The value cannot be longer than 50  characters'], 
    }, 
     { 
        number_1: ['The value needs to be  less than or equal to 50'], 
    }, 
); 

There can be several validation error messages for each context or View context field. If an error message with the same text is added for a context field with the same code, the duplicate is ignored. Example usage in a validation function:

const result = new ValidationResult();
if ( !Context.data.stringname || Context.data.stringname.length < 10) { 
     result.addContextError('stringname', 'The value needs to be at least 10  characters long'); 
} 
if (!ViewContext.data.number_1 ||  ViewContext.data.number_1 > 50) { 
    result.addViewContextError( 'number_1', 'The value needs to be shorter than or equal to 50 characters');  
} 
return result;
