count occurrences of character in string javascript

var temp = "This is a string.";
var count = (temp.match(/is/g) || []).length;

Output: 2

Explaination : The g in the regular expression (short for global) says to search the whole string rather than just find the first occurrence. This matches 'is' twice.

Count Total Amount Of Specific Word In a String JavaScript

Here are two methods (Scroll down please here!) to find the total number of occurrence match
words in the string.

The first function allows you to give a query as input.
The second one uses the .match function of JavaScript.

Both introduced methods are resistant for any chars and 
independent of splitter and separator like " " or ",".

str1 is your query

str1 = "fake";  

str2 is the whole string:

var inputString = "fakefakefakegg fake 00f0 221 Hello wo fake misinfo
fakeddfakefake , wo  431,,asd misinfo misinfo co wo fake sosis bandari
mikhori?, fake fake fake ";

Method 1 : use .indexOf or .search function of JavaScript 
(advantage you can give input)

function CountTotalAmountOfSpecificWordInaString(str1, str2)
    let next = 0;
    let findedword = 0;
        do {
            var n = str2.indexOf(str1, next);
            findedword = findedword +1;
            next = n + str1.length;
            }while (n>=0);
     console.log("total finded word :" , findedword - 1 );
     return findedword;
Method 2 : use .match function of JavaScript:

 * @return {number}
 *  you have to put fake as query manually in this solution!!! disadvantage

function CountTotalAmountOfMachedWordInaString(str2) {
    let machedWord = 0;
    machedWord = str2.match(/fake/g).length; 
    console.log("total finded mached :" , machedWord);
    return machedWord;
call the functions (Inputs):

CountTotalAmountOfSpecificWordInaString("fake" , "fake fakefakegg fake 00f0 221 Hello wo fake rld fakefakefake , wo lklsak dalkkfakelasd co wo fake , fake fake fake" );
CountTotalAmountOfMachedWordInaString("sosis bandarie fake  khiyarshour sosis , droud bar fake to sosis3");
