E0100: missing semicolon between condition and update parts of for loop

C-style for loops require two semicolons: one ; between the init and the condition, and one ; between the condition and the update expression. It is a syntax error to omit the ; between the condition and the update expression:

for (let i = 0; i < 100 ++i) {
  console.log(i % 15 ? i : "FizzBuzz");
}

To fix this error, insert a semicolon (;) after the condition:

for (let i = 0; i < 100; ++i) {
  console.log(i % 15 ? i : "FizzBuzz");
}
