This example shows how we can join an array into a string using the join method.

Its a nice quick way to convert your array into a string with a delimiter such as , or ;

Here we can see the test array in console:

And then under it the array converted to a string with the join method.

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);

In this case my anchor this week becomes driving almost 2hrs outside of Atlanta to one of my favorite hard core gyms in the world.. MetroFlex aka The Dungeon. The gym owners turn the heat way up so it becomes a fun sweat box and the gym members just watch from afar and leave me alone. I happily drive myself long distances to find MY ANCHOR. Our anchor allows us to have balance, focus and be as productive as possible. And if you're in the middle of a heavy set and your headphones start to fall off your head, like mine did here.. well.. f*ck the headphones. Let em break and fall. You can always get a new pair, but the iron ain't ever gonna lift itself.
