This function is useful if you want the ordinal of a number. i.e 21st or 11th.
function ordinal(n){
ord = [, 'st', 'nd', 'rd'][n%10];
nth = ([11, 12, 13].includes(n%100) || ord === undefined) ? 'th' : ord;
return n + nth;
}
Great when dealing with dates.

Thank you for the great content, master. Tell me, what do you use for editing and screenfiliming?

[anaycoding]

the 2nd tip can be used for other things but for the function default you can just do this:
```
function doSomething(x = 32) {
console.log(x);
}
```
so the default for x would be 32

You use examples from documentation, but without explaining. What the point of video?
