E0101: missing body for do-while loop

do-while loops require a body, which must be a statement or { } surrounding a list of statements. It is a syntax error to omit the body of a do-while loop:

function skipNumber(parser) {
  do
  while (isDigit(parser.peek()));
}

do while (queue.length > 0) {
  queue.pop().run();
}

To fix this error, write the body of the do-while loop:

function skipNumber(parser) {
  do parser.next();
  while (isDigit(parser.peek()));
}

Alternatively, remove the extraneous do keyword:

while (queue.length > 0) {
  queue.pop().run();
}
