I'm eager to delve deeper into the error message I encountered:
The conversion of type 'A' to type 'B' may be problematic because these types do not accurately overlap.
As I conducted some tests, a peculiar error arose.
Behold my code snippets:
type User = {
id: string
username: string
age?: number
}
const user1 = {
id: '123',
username: 'user',
} as User // Success
const user2 = {
id: '123',
username: 'user',
age: 5
} as User // Success
const user3 = {
id: '123',
username: 'user',
age: 5,
email: '1234'
} as User // Success
const user4 = {
id: '123',
username: 'user',
age: '5',
} as User // Error due to mismatched age data type
Initially, these tests seemed simple enough.
However, when I attempted the following:
const user5 = {
username: 'user',
age: 5,
} as User // Passes even without an ID field
// Odd occurrence
const user6 = {
username: 'user',
age: 5,
email: '123'
} as User // Fails, despite the presence of unknown fields minus the ID
`
Upon examining user5, the assertion holds true. But with user6, it fails - leaving me perplexed. I would greatly appreciate any insights or clarifications on this matter. Thank you.
