E0109: for-of loop expression cannot have semicolons
There are three kinds of for
loops: C-style for
loops (;
), for
-in
loops, and for
-of
loops. It is a syntax error to write a for
-of
loop
with a ;
:
for (let i of 0; i < 100; ++i) {
console.log(i % 15 ? i : "FizzBuzz");
}
for (const benchmark of collectBenchmarks();) {
runBenchmark(benchmark);
}
To fix this error, remove the of
keyword in the C-style for
loop:
for (let i = 0; i < 100; ++i) {
console.log(i % 15 ? i : "FizzBuzz");
}
Alternatively, remove the extra ;
:
for (const benchmark of collectBenchmarks()) {
runBenchmark(benchmark);
}
