search for a character in a string in Javascript

let search_char = (string, character) => {
  let count = 0;
  for (let i = 0; i < string.length; i++) {
    if (string.charAt(i) === character) {
      count++;
    }
  }
  return count;
};

This code uses a function to search for a specific character in a string by looping through each character in a string and comparing it to the specified character. It starts by declaring a variable called count and assigning it the value of zero. This variable will be used to count the number of times the character appears in the string.

Inside the function, the loop will traverse each character of the string using the charAt function. Each time it finds a character that matches the specified character, it will increase the count variable by one.

Finally, it will return the value of count, which is the number of times the character appears in the string.
