How to convert a ternary operator into a conditional operator?-CodePudding

Basically I need to transform a ternary operator into a conditional operator using "if...else" cycle.

function getBestStudent (students) {

const bestAverageMark = students.reduce((a, b) => getAverageMark(a) > getAverageMark(b) ? a : b)

return bestAverageMark
}

"getAverageMark" here is another function.

How can I transform this into a conditional operator "if... else"? Thank you!

CodePudding user response：

you might wanna check out the mdn docs on arrow function expressions

function getBestStudent (students) {
  const bestAverageMark = students.reduce((a, b) => {
     if (getAverageMark(a) > getAverageMark(b)) {
       return a;
     } else {
       return b;
    }
  });

  return bestAverageMark;
}

this could be simplified to

function getBestAverageMark (a,b) {
  if (getAverageMark(a) > getAverageMark(b)) {
    return a;
  } else {
    return b;
  }
}

function getBestStudent (students) {
  return students.reduce(getBestAverageMark);
}
