How to find the largest numbers in an unordered array-CodePudding

I need to find the largest number in an unordered array (javascript)

[[-34, -54, -74], [-32, -2, -65], [-54, 7, -43]]

This should be the result -> [-34, -2, 7]

I have tried this:

let brojevi = [
  [-34, -54, -74],
  [-32, -2, -65],
  [-54, 7, -43]
];

let pronadjiNajveciBroj = (brojevi) => {
  let najveci = brojevi[0];
  for (let i = 0; i < brojevi.length; i  ) {
    if (brojevi[i] > najveci) {
      najveci = brojevi[i];
    } else {
      console.log("Ovo nije najveci broj")
    }
  };

  return {
    najveci
  };
};
console.log(pronadjiNajveciBroj(brojevi));

but I only get the last array as a result

CodePudding user response：

const a = [[-34, -54, -74], [-32, -2, -65], [-54, 7, -43]];
const r = a.map(e=>Math.max(...e));
console.log(r);

a.map() takes an array and returns another array formed by transforming each element (an array in this case) with a function.

Math.max() takes a list of comma-separated values and returns the maximum value.

The spread operator ... yields a list of comma-separated values from an array.
