计算字符串数组中的子字符串

Question

I would like to count the number of use of Mr and Miss in the array.

I'v started with one of them and been trying a couple of solutions.

But I can't get my head around how to sum the counts of the whole array, like when I console.log it, it will print each one of them, not the sum of all Mr in the array?

const array = [
  "Hello Mr, Hello Miss",
  "Hello Mr, Hello Miss",
  "Hello Mr, Hello Miss",
  "Hello Mr, Hello Miss"
];
console.log(array);

array.forEach((object) => {
  var count = (object.match(/Miss/g) || []).length;
  console.log("Number:", count);
});
```

Answer 1

 const array = [ "Hello Mr, Hello Miss", "Hello Mr, Hello Miss", "Hello Mr, Hello Miss", "Hello Mr, Hello Miss" ]; console.log(array); const count = (array.join(' ').match(/Miss|Mr/g) || []).length; console.log(count);
