const array = ["john", "mark", "sally", "adam", "rick"]
const newArray = //the index values between array[0] and array[2]
//newArray= ["john", "mark", "sally"]
我将如何继续获得该价值？有方法的特定功能吗？或者，我可以将指定的索引值转换为字符串吗？例如：
const newString = //the index values between array[0] and array[2]
//newString= "johnmarksally"
您可以使用array.slice和array.join
const array = ["john", "mark", "sally", "adam", "rick"]
const newArray = array.slice(0, 3);
console.log(newArray);
const newString = newArray.join('');
console.log(newString);本文收集自互联网，转载请注明来源。
