We are required to write a JavaScript function that finds how many times a specific letter is appearing in the sentence
Example
Let’s write the code for this function −
const string = 'This is just an example string for the program'; const countAppearances = (str, char) => { let count = 0; for(let i = 0; i < str.length; i++){ if(str[i] !== char){ // using continue to move to next iteration continue; }; // if we reached here it means that str[i] and char are same // so we increase the count count++; }; return count; }; console.log(countAppearances(string, 'a')); console.log(countAppearances(string, 'e')); console.log(countAppearances(string, 's'));
Output
Following is the output in the console −
3 3 4
