Descrizione
TypeScript Version: 4.1.2
Search Terms: downlevelIteration, string, spread
Code
function test(name: string) {
for (const _char of [...name]) {
}
}
Run tsc on just this ts file with no extra flags (I couldn't find the right combination of playground checkboxes to simulate this.
Expected behavior: Assuming the code is wrong, the error message should probably not say that string is not a string type.
Actual behavior:
error TS2569: Type 'string' is not an array type or a string type. Use compiler option '--downlevelIteration' to allow iterating of
iterators.
