In this article, I will introduce how to use the array join() method in JavaScript.
The join() method
You can use the join() method to join each element in the array to create a new string.
The syntax is below.
array.join()
//or
array.join(separator)
array.join()
If no argument is specified, a comma is specified as the separator.
Below is a sample.
const array = ["Apple", "Banana"];
console.log(array.join());
//"Apple,Banana"
array.join(separator)
If you specify a separator, all elements in the array are joined with the specified separator.
Below is a sample.
const array = ["Apple", "Banana", "Lemon"];
console.log(array.join(""));
//"AppleBananaLemon"
console.log(array.join(" "));
//"Apple Banana Lemon"
console.log(array.join(", "));
//"Apple, Banana, Lemon"
console.log(array.join(" + "));
//"Apple + Banana + Lemon"
