This PR switches our representation of type mappers from functions (that close over state) to objects. This brings greater transparency to the actual mappings performed by type mappers and enables more efficient construction of composite mappers.

The PR improves performance by up to 1% (with a 9% outlier on older versions of Node.js) and memory usage by up to 8%.

Some questions for my own edification.

function createReplacementMapper(source: Type, target: Type, baseMapper: TypeMapper): TypeMapper {
return t => t === source ? target : baseMapper(t);
function addTypeMapping(mapper: TypeMapper | undefined, source: TypeParameter, target: Type) {
return mapper && mapper.kind === TypeMapKind.Simple && mapper.source2 === mapper.target2 ?

I'm getting mixed up. When you combine two maps, you look in the first map first and then, if you find something, do you stop looking or apply the second map to the first target? From the handling of composite maps ingetMappedType it seems like it might be the latter, but this appears to do the former for unary maps?

The particular test here is to see if the second source/target pair in the simple mapper is unused (recall, when source and target are the same, we have a no-op). If so, we create a new simple mapper with both source/target pairs in use.

One added twist with composite mappers is that the first mapper may map to some type that the second mapper further maps. For example, the first mapper might map fromT toU[] and the second mapper fromU tostring. This also explains why we directly call thegetMappedType with the first mapper, but then callinstantiateType with the second one.

I should add, in theaddTypeMapping case, we actually don't care about the ability for the second mapping to affect the first mapping, which is why we can do the simple mapper optimization.

So maps are combined by composition, but we happen to know that this particular composition is equivalent to concatenation?

case TypeMapKind.Array:
return makeArrayTypeMapper(baseMapper.sources, map(baseMapper.targets, (t, i) => baseMapper.sources[i] === source ? target : t));
}
return makeFunctionTypeMapper(t => t === source ? target : getMappedType(t, baseMapper));

Depending on how badly I've mixed up composite maps (see my question above), this seems like it might be equivalent to a composite map withsource-to-target on the left hand side?

Not quite. We don't want the second mapping to be applied to the result of the first. We basically just want to replace one of the mappings in the second mapper, which we can do by putting a check in front of the second mapper.

How come this transformation (concatenation?) wasn't interesting enough to become aTypeMapKind?

Does it make sense to recognize theidentityMapper singleton in prepend/append/merge and short-circuit the construction of a composite mapper, if it's found?


function makeBinaryTypeMapper(source1: Type, target1: Type, source2: Type, target2: Type) {
return (t: Type) => t === source1 ? target1 : t === source2 ? target2 : t;
function getMappedType(type: Type, mapper: TypeMapper): Type {

I kinda-sorta wanna preemptively make this a loop rather than a recursive function to better optimize the recursive cases, but... it's not strictly required.

I looked at that, but just makes the code more complex for no appreciable gain.
