getKeyPath- A type-safe function to get a key-path.getValueByKeyPath- A function to extract the value by a given key-path.setValueByKeyPath- A function to set the value by a given key-path.
const customer = {
name: 'John Doe',
addresses: [
{ street: '123 Main St', city: 'Anytown' },
{ street: '456 Elm St', city: 'Anytown' },
] as const,
}
const keyPath = getKeyPath<typeof customer>('addresses.0.street') // 'addresses.0.street'
const value = getValueByKeyPath(customer, 'addresses.0.street') // '123 Main St'
setValueByKeyPath(customer, 'addresses.0.street', '180 Azadi St')
