if (typeof dest === Array) {

When transpiling in typescript, the 'if' statement:
if (typeof dest === Array)
returns the error:
TS2367: This condition will always return 'false' since the types 'string' and 'ArrayConstructor' have no overlap.
I believe the statement should be changed to
if (dest instanceof Array)
as is done elsewhere in the code.
