how to count individual repeated word in a text, not repeated character in a text...

Question

-I try using:
function countWord(string, word) {
return string.split(word).length - 1;
}
var text="We went down to the stall, then down to the river today.";
var count=countWord(text,"to");
console.log(count);//3
-result is 3 instead of 2(how to fix this in es6);

Answer 1

use regexp to detect word boundaries:

split(new RegExp("\\b"+word+"\\b"))

or, split string into words by splitting at spaces and count matching words ^^

return string.split(" ").filter(w => w==word).length;

you could improve last code by using regexp too, and split at consecutive spaces and/or not letters char...

split(/\s+/)

split(/[^a-z]+/i)

Answer 2

var countWord = (string, word) => string.split(" ").filter(w=>w===word).length;

Answer 3

Your function has split the text into four parts because the word today also has a to. ☺️
You need to first select words from the text, and only then count the desired word.

Answer 4

" to " not "to"
also check if text begins with "to " or ends with " to"
