Basic Join Usage

Here is the basic usage for join, where you can specify the delimiter in the example i have used the comma ,

Javascript

let my_string = my_array.join(",");

Javascript

/* define the array */
let my_array = ["birds", "frogs", "peanuts"]; 

/* check the array is valid in console */
console.table(my_array); 

/* join the array into a string called my_array_string and add , inbetween each item. */
let my_array_string = my_array.join(",");

/* check if the new string is valid */
console.log(my_array_string);
