Makes sense, added min as Math.min and Math.max differences surprised me a few times. Will go ahead and add a few others

// Math.min(value0, ..., valueN)
addFunction(DEFAULT_SHAPES, [], {
positionalParams: [],
restParam: Effect.Read,
returnType: {kind: 'Primitive'},
calleeEffect: Effect.Read,
returnValueKind: ValueKind.Primitive,
}),
],
]),

I debated on adding window but figured we should leave it out for now. I wonder if we want to handle window and document separately as people often use these for DOM-manipulation (global mutable state)

addObject(DEFAULT_SHAPES, 'global', TYPED_GLOBALS),
);
