We create two strings initially- a vowel string which contains all the vowels and a cons string containing all 26 English alphabets. We also initialize a variable n to zero. 

We convert the given string to lowercase using Javascript's toLowerCase() function.

We then loop through the every element of given string and check if the element is a part of const string to avoid any special character or spaces. Then we check if the value of that element compared to vowel string is equal to -1. If it is then it proves that the element we are comparing is an English alphabet but not a vowel. In that case we increment the value of n by 1. We continue this process for every character of the input string and then after the loop we output the value of n as our consonant count.
