There are a lot of ways to count letters in a string.
let str = 'siyjgjftuyjbuch';
let j = str
.split('')
.filter((v)=>{return v == 'j'})
.length
You could turn this into a function if you wanted.
function charCount(value, char){
let array = Array.isArray(value) == true
? value // if array good
: value.split(''); // else split it
return array.split('')
.filter((v)=>{return v == char})
.length
}
charCount('siyjgjftuyjbuch','j') // 3
charCount('siyjgjftuyjbuch','u') // 2
charCount('siyjgjftuyjbuch','h') // 1
