I came across the following code written in js FlowType (I am interested to know the value of + in the context of FlowType not in general JS).
Could you please explain me what does the +
symbol mean in front of the property in the code below:
export type User = {
+name: string,
+surname: string,
+personId: PourceId,
}
I could not find any reference in the documentation, any link is also welcome.
