Converting Arrays to Strings
The JavaScript method toString() converts an array to a string of (comma separated) array values.
Example const fruits = ["Banana", "Orange", "Apple", "Mango"]; let fruitsString = fruits.toString(); console.log(fruitsString); Result: Banana,Orange,Apple,Mango
The join() method also joins all array elements into a string.
It behaves just like toString(), but in addition you can specify the separator:
Example
const fruits = ["Banana", "Orange", "Apple", "Mango"];
let fruitsJoin = fruits.join(" * ");
console.log(fruitsJoin);
Result: Banana * Orange * Apple * Mango
Popping and Pushing
When you work with arrays, it is easy to remove elements and add new elements.
This is what popping and pushing is:
Popping items out of an array, or pushing items into an array.
JavaScript Array pop()
The pop() method removes the last element from an array:
Example
const fruits = ["Banana", "Orange", "Apple", "Mango"];
fruits.pop();
Result:
["Banana","Orange","Apple"]
The pop() method returns the value that was “popped out”:
