Discord js splice arguments9/11/2023 ![]() ![]() This greatly simplifies the creation of new commands. So, as your next step, consider looking at making A Basic Command Handler. At this point, "parsing arguments" becomes something you might realize is necessary for all of your commands, and writing "(command = 'thing')" for every command is dull and boring. Now, there's most definitely always room for some optimization, and better code. Based on your question, you have a lot to learn and there is way too much to explain to you regarding having a number argument, restricting it with a min and max value, or restricting it to a list of choices which are autocompleted for the user. shift() function to remove the first element (. To access part of an array without modifying it, see slice (). This will firstly split the empty spaces (arguments) into a variable called array. To create a new array with a segment removed and/or replaced without mutating the original array, use toSpliced (). But !newtag First Var Second Var Third Var could work by removing the command, splitting by then splitting by space. The splice () method changes the contents of an array by removing or replacing existing elements and/or adding new elements in place. When only one argument is provided, all the items after the provided. For example, !newtag First Var Second Var Third Var won't work. splice() methods need at least one parameter to remove an element from the array. Ideally, if you need more than one argument with spaces in it, do not use spaces to split the arguments. If you're thinking, "What if I have more than one argument with spaces?", yes that's a tougher problem. For example, these 2 very basic commands: destructuring on the v-for item alias similar to destructuring function arguments. We can simplify this by looking only at the command variable itself. The variable scoping of v-for is similar to the following JavaScript. So now that we have our command variable, we no longer need to use the if ((prefix+'command')) for every command. toLowerCase() so our command is always in lowercase, meaning !Ping, !ping and !PiNg will all work. The examples we've covered so far have all been fairly simple commands, such as ping, server, and user which all have standard static responses. This gives us mycommand that's returned, and the args array becomes only JavaScript provides users with various methods and properties for string manipulation, to transform those strings or to search useful information from those. args.shift() where shift() will remove one element from the array and return it.This means that mycommand arg1 arg2 arg3 will work just as well as if they only had 1 space. Why not just by space? Because sometimes especially on mobile, you might have an extra space before or after mentions, or just straight up to an extra space by mistake. With this, npm run build will generate HTML, JS and CSS files inside the dist directory. split(/ +/g) splits the string by one or many spaces. Dont be shy about asking for help in the Discord chatroom. trim() ensures there's no extra spaces before/after the text. slice(prefix.length) removes the prefix such as ! or + from the message content, leaving mycommand arg1 arg2 arg3. Let's break this down into what it actually does, line by line.
