Suppose I define a new Object type:
interface NEWOBJECT {
name: {};
}
Is it possible to have the 'name' property in NEWOBJECT be able to accept either 'name1' or 'name2', allowing me to create instances of NEWOBJECT with different names as the property value?
For example, like this:
var object1: NEWOBJECT = {name1: {}};
var object2: NEWOBJECT = {name2: {}};
Thank you.
Affirmative
type FRESHITEM = {
[X in 'item1' | 'item2']?: {};
}
I regret to inform you that this setup still allows for both properties to be present or absent, so I recommend taking a more precise approach using union types instead.
interface FRESHITEM1 {
item1: {};
}
interface FRESHITEM2 {
item2: {};
}
type FRESHITEM = FRESHITEM1 | FRESHITEM2;
Ensure your TypeScript is up-to-date.
When assigning a type, it is essential to use properties with identical names. However, you have the flexibility to define optional properties as well. This allows you to assign your variable with any of these optional properties.
interface CUSTOMOBJECT {
property1?: {};
property2?: {};
}
