By implementing prop validation options, we can specify type requirements for individual props. This has no implication in production but throws warnings during the development phase, thereby helping the developer identify potential issues with incoming data and the particular type requirements for a prop. 

An example of configuring three props:

props: {
    accountNumber: {
        type: Number,
        required: true
    },
    name: {
        type: String,
        required: true
   },
   favoriteColors: Array

}
