[JsWord] is an interned string.
|
|
|
|
This type should be used instead of [String] for values, because lots of
|
|
values are duplicated. For example, if an identifier is named `myVariable`,
|
|
there will be lots of identifier usages with the value `myVariable`.
|
|
|
|
This type
|
|
- makes equality comparison faster.
|
|
- reduces memory usage.
