Write a function to quote a string:

function quote(s) {
  return typeof s === 'string' ? "'"+s+"'" : s;
}

Now map your array and paste the elements together with a ma:

data . map(quote) . join(',')

Since joining with a ma is the default way to convert an array into a string, you might be able to get away without the join in some situations:

alert (data . map(quote));

since alert converts its parameter into a string. Same with

element.textContent = data . map(quote);

if data is an array defined as

var data = [];
data.push('abc');
data.push(21);    
data.push('email');

the use join() method of array to join (concatenate) the values by specifying the separator

try

alert( "'" + data.join("','") + "'" );

or

console.log( "'" + data.join("','") + "'" );

or simply

var value =  "'" + data.join("','") + "'" ;
document.body.innerHTML += value;

Now data = ['abc', 21, 'email'];

So we can use forEach function

var myString = '';

data.forEach(function(value, index){
   myString += typeof value === 'string' ? "'" + value + "'" : value;
   if(index < data.length - 1) myString += ', ';
});

console.log(myString)

Shorter version:

myString = data.map(function(value){
   return typeof value === 'string' ? "'" + value + "'" : value;
}).join(', ');

console.log(myString);
