    emokValidator.addField({
        fieldName: 'firstName',
        type: 'string',
        value: "Mokhtar",
		op:"and" // One rule is enough or all must be TRUE.
        validators: [
			// We can define a sync or async custom function
			{
				 validator:(v)=>{
					 return v.length >5 ? true : false;
				 },
                err: 'custom error' 
			},
			// We can define an asynchronous custom function
			{
				validator:async(v)=>{
					 const name = await getDbName(v);
					return v===name?true : false;
				 },
                err: 'custom error'

			// We can use the functions available in the Validatorjs or Validatejs or PersianTools library.
            {
                validator: 'isAlpha',
                options: ['fa-IR', { ignore: "-_،  آ.," }],
