Javascript Array convert to String

Introduction

There are two functions that return string representations of an array:join() and toString().

Both functions return a string containing the elements of the array delimited by commas.

Here are some examples: 

let names = ["David", "Cynthia", "Raymond", "Clayton", "Mike", "Jennifer"]; 
let namestr = names.join(); 
console.log(namestr);  // David,Cynthia,Raymond,Clayton,Mike,Jennifer 
namestr = names.toString(); //from w w  w. ja  v  a  2 s.co m
console.log(namestr); // David,Cynthia,Raymond,Clayton,Mike,Jennifer
