How can i get an 'number' input in discord.js

Question

I want to make a basic calculator in 'discord.js', but the calculating command doesn't work. Main input command is ':hiz'. When someone types something like ':hiz 5' it should add 10 to 5.

    if(message.content == ':hiz ')
{
    var input = message.content;
    var sayi = input.substr('4');
    console.log(sayi);
}

That is the code that i tried. It doesn't get the number that inputted. Is there an another way to do it?

Answer 1

您应该检查message.content.startsWith(':hiz ')而不是message.content == ':hiz ' 。
