为什么这段代码没有显示我想要的结果？ [已关闭]

Question

let numArr2 = [1, 2, 3, 4, 5, 6, 7];
numArr2.splice(1, 1);
console.log(`Length of the numArr2 is ${numArr2.length()}`);

为什么这段代码没有显示

numArr2

的长度？

Answer 1

长度是一个正确的值，而不是一个方法，请删除括号。

let numArr2 = [1, 2, 3, 4, 5, 6, 7];
numArr2.splice(1, 1);
console.log(`Length of the numArr2 is ${numArr2.length}`);
