You almost had it. Try this:

array.map(x => "'" + x + "'").toString();

Variable names like array and string are probably...akin to bad etiquitte, but I got'chu:

var anArray = [ "f", "test" ];
var theString = "'" + anArray.join("','") + "'";

Using ES6 with string interpolation and arrow function.

You can use join() or toString() to display each item separated by a comma

var array = ["f","test"];
console.log(array.map(x=>`'${x}'`).join(','))
console.log(array.map(x=>`'${x}'`).toString())

Let's use Map in JS

var result = ["f","test"].map(function(b) { 
   return "'" + b + "'"; 
}); 
console.log(result.toString());

1. using JavaScript Array.join() method : It will join all elements of an array into a string.

DEMO

var array = ["f","test"];

var res = "'"+array.join("','")+"'";

console.log(res);

2. using ES6 spread(...) operator : It allows an expression to be expanded in places where multiple arguments (for function calls) or multiple elements (for array literals) or multiple variables (for destructuring assignment) are expected.

DEMO

let array = ["f","test"];

function printString(a,b) {
  var str = `'${a}','${b}'`;
  return str;
}

var res = printString(...array);
console.log(res);

3. using Array.map() method with ES6 syntax - It creates a new array with the results of calling a provided function on every element in this array.

DEMO

var array = ["f","test"];

var str = array.map(item => "'" + item + "'").join();

console.log(str);

I believe you want your ouptut as a string and not as array and code to be written such that it is supported by all browser (no ES6). So I have tried to keep it as simple as possible:

var arrayTest = ["f","test"]
var str  = arrayTest.map(function(obj) {return("'" + obj + "'")}).toString();
