I found this very informative post on the subject of the Javascript SORT method. I found, however, that VS Code does not recognize the method.
This is the error message I got:
numbers.sort((a,b) => a - b); ^
TypeError: numbers.sort is not a function
Has anyone else run into this?

That error looks like the type that you get when your
numbersvariable is not actually typed as an Array.For example, if you have some code where the numbers variable was an object or an integer or a string:
You will get
Uncaught TypeError: numbers.sort is not a functionbecause there is no sort function for strings.But if you check this exact snippet of code:
You should definitely not see any errors.
When you say:
This makes me think you are seeing IDE debugging warnings which could also be due to other problems with the your VS Code and extensions config.
But my first recommendation on debugging would be to check the TYPE of the
numbersvariable just before you callnumbers.sort()and confirm that it is an Array
