In my recent coding endeavor, I've crafted the following function:
function extend(obj, key, value) {
return { ...obj, [key]: value }
}
Ideally, I want to utilize this function in a versatile manner, with obj representing an Object of which the type will be identified at the callsite, key as a constant string at the callsite, and value standing for a value whose type is known during the call. The existing obj may or may not contain the specified key, and the former value linked to that key could differ from the new value.
Exploring the Utility Types reference, no suitable option seems available to define a relevant type for extend. Is there a viable solution to address this challenge?
