Assignability in Go refers to the ability of a value to be assigned to a variable or a constant of a certain type. In other words, it determines whether a value can be assigned to a variable or a constant of a specific type, based on the rules defined by the Go language.
In Go, assignability is determined by a set of rules that define which values can be assigned to a variable or a constant of a certain type. These rules are based on the type hierarchy in Go, and they ensure that values are assigned only to variables or constants that can safely store them.
For example, a value of type int can be assigned to a variable or a constant of type int, but it cannot be assigned to a variable or a constant of type string, because these two types are not compatible.
