for对象数组上的每个循环

Question

我一直试图让它通过所有的for循环，但它总是说数组。。text每当我尝试获取数组中的任何元素时，行/消息都是未定义的。

我想得到整个对象，并使用split("(从文本中得到每个字母。每当我查看控制台日志，试图从数组中获取任何内容(甚至其长度(时，都会说它是未定义的，但每当我将数组放入其中时，它都会正常显示对象数组。如何使定义数组中的元素(对象(？？

function say(messages = [{text: ' ', speed: 90, pause: false, colour: ['RED//BLUE']}]){        
let alphabets = [];                                  
let textLines = messages
console.log(textLines.length)

textLines.forEach((line, i) => {                       
if (i < textLines.length - 1)  line.text += " ";        

console.log(typeof textLines[1])
line.text.split("").forEach((alphabet) => {        
let span = document.createElement("span");
span.textContent = alphabet;                       
textContainer.appendChild(span);
alphabets.push({                                  
span: span,
isSpace: alphabet === " " && !line.pause,
delayAfter: line.speed,
classes: line.classes || []
});
});
});
function revealLetter(list) {
let nextLetter = list.splice(0, 1)[0];        
nextLetter.span.classList.add("revealed");        
nextLetter.classes.forEach((c) => {
nextLetter.span.classList.add(c);       
});
let delay = nextLetter.isSpace && !nextLetter.pause ? 0 : nextLetter.delayAfter;        

if (list.length > 0) {
setTimeout(function () {         
revealLetter(list);
}, delay);      // the delay is the talking speeds
}
}
setTimeout(() => {        // to start the loop
revealLetter(alphabets);   
}, 600)

}

say({             // can change what's said, the colour of text, the speed its displayed and if there's a pause (4 things)
messages: [
{text: 'Literally what does that even mean???',
speed: talkingSpeeds.fast,
pause: false,
},
{text: 'Like. what?',
speed: talkingSpeeds.normal,
pause: true
},

{text: 'Stop talking.',
speed: talkingSpeeds.slow,
pause: true,
colour: ['red']
}
]
})

这个问题有两种解决方案：

1. 或者你可以在say函数中发送数组，比如：

   比如([…](

2. 或者你可以在say函数中更改你接受的参数，比如：

   函数say(｛messages=[｛text:"，速度：90，暂停：false，颜色：[‘RED//BLUE’]｝]｝(｛…｝
