Better pattern for updating model

updateField.js

// This way is needlessly verbose
export default class CustomerNameComponent {
  customer = new Customer()

  // Annoying boilerplate
  updateCustomerName = (text: string) => {
    this.customer.name = text  
  }
  
  render() {
    return (
      <TextInput onChangeText={this.updateCustomerName} />
    )
  }
}


// Instead, use the `updateField` helper so you don't need a new function for every input
import { updateField } from 'lib/meta'
export default class CustomerNameComponent {
  customer = new Customer()
  
  render() {
    return (
      <TextInput onChangeText={updateField(this.customer, 'name')} />
    )
  }
}
