E0089: with statement needs parentheses around expression

with statements have an expression after the with keyword. It is a syntax error to write an expression without ( and ):

with person {
  console.log(`Hi, ${firstName} ${lastName}!`);
}

To fix this error, write ( before the expression and ) after the expression:

with (person) {
  console.log(`Hi, ${firstName} ${lastName}!`);
}
