    Get the current version of Docker Compose installed on my macOS machine?

    If you execute this command:

    docker-compose --version
    

    It should output the version of the docker-compose installed to your machine:

    Docker Compose version 2.4.1
    

    If docker-compose isn't installed on your machine, you'll receive an error message instead.

    Remove any spaces from the start and/or end of a string?

    Here's a couple options you can use for removing the trailing/ending spaces from your strings.

    Option 1:

    trim() method built into JavaScript:

    string.trim()
    

    Supported by all browsers besides Internet Explorer.

    Option 2:

    You can also use a regular expression:

    string.replace(/^\s+|\s+$/g, "")
    

    This could be used like this:

    let string = "   A string.   "
    string = string.replace(/^\s+|\s+$/g, "")
    
    // "A string."
    

    Supported by all browsers.
