<h1>Function overload</h1>
|
|
|
|
> Author: Thomas Laforge

|
### Information
|
|
|
|
Angular uses TypeScript, and mastering TypeScript can help you avoid runtime errors by catching them at compile time.
|
|
|
|
In this challenge, we have a function to create a vehicle. However, each vehicle type requires different mandatory properties.
|
|
Currently, we are getting an error at runtime if one property is missing and we don't get the return Type, which is not ideal.
|
|
One solution would be to create a separate function for each vehicle type, but for this challenge, I want to use the same function and have TypeScript automatically complete the properties depending on the type passed as the first parameter.
|
|
|
|
To achieve this, we will use overload functions.
|
|
|
|
### Statement
|
|
|
|
- Use function overload
