How to count the total number of letters or characters inside of an array in Javascript-CodePudding

Part of a JavaScript program I am writing asks to count the total number of the letters from the array objects. So for example if I had an array like this.

["apple", "pear"]

The total count of letters would be 9. I am not sure if their is a char count function in JavaScript and a lot of the examples I have seen on here only count the occurrences of individual letters. Any help with this would be appreciated.

There are a few ways you could do this, but I think the following is a good one:

var x = ["apple", "pear"];
var result = x.map(a => a.length).reduce((a, b) => a   b);
console.log(result)

This uses the map function to turn x into an array of each item's length, in this case [5, 4]. Then sums that array using the reduce function.

You can use forEach to get length of every element in your array, then add it to a var.

let charCount = 0;
const array = ["apple", "pear"];
array.forEach(e => {
  charCount  = e.length;
});
console.log(charCount);
