javascript中这些变量有什么区别

Question

A function in my program takes the variable DAT and when I try passing args through it fails. I am pretty sure DAT is a JSON and args is array. How would I change args to same variable type as DAT .

here is my code:

const args = message.content.match(/\b[^"]+\b|(?!")\S+/g);
const command = args.shift().toLowerCase().slice(prefix.length);


if(command === 'hello'){
    message.channel.send("I only research leave me alone");
    let DAT = ['AAPL', 'PYPL', 'GOOG', 'A'];
    console.log("dat: " + DAT);
    console.log("args: " + args);
    console.log(DAT, args);
}
else if(command === 'research'){

    let DAT = ['AAPL', 'PYPL', 'GOOG', 'A'];
    stockdata.realtime({
        symbols: DAT,
        API_TOKEN: world_token
    })
    .then(response => {
        //console.log(response);
        //console.log("symbol" + response.symbols_returned)

    })
    .catch(error => {
        console.log("error");
    });

}

the result in console

PS C:\Users\gaming pc\bot_code\researchbot> node index.js
ready
dat: AAPL,PYPL,GOOG,A
args: 
[ 'AAPL', 'PYPL', 'GOOG', 'A' ] []
dat: AAPL,PYPL,GOOG,A
args:  AAPL PYPL GOOG A
[ 'AAPL', 'PYPL', 'GOOG', 'A' ] [ ' AAPL PYPL GOOG A' ]

Answer 1

Your regular expression will produce only a single match for your example, ["AAPL PYPL GOOG A"] . This happens because your regex is non-greedy. Without knowing exactly what you meant, I won't try to fix your regex; but /\\S+/ is sufficient to solve the problem you presented here.

Answer 2

I used an expression from my other bot so I just changed the expression

const args = message.content.slice(prefix.length).split(/ +/);
const command = args.shift().toLowerCase();
