You can follow these steps for check of key object

Compare each and every element of two arrays.
Return the matched element.
Add the element or object into the object of array.

Check this example :

let Joi = require('joi')
let service = Joi.object().keys({
  serviceName: Joi.string().required(),
})

let services = Joi.array().items(service)

let test = Joi.validate(
  [{ serviceName: 'service1' }, { serviceName: 'service2' }],
  services,
)
