Step 1: Go to https://www.youtube.com/feed/channelsand scroll to the bottom of the page to populate all items to the screen.
第 1 步：转到https://www.youtube.com/feed/channels并滚动到页面底部以将所有项目填充到屏幕上。
Step 2: Right-click anywhere on the page and click "Inspect Element" (or just "Inspect"), then click "Console", then copy–paste the below script, then hit return.
第 2 步：右键单击页面上的任意位置并单击“检查元素”（或仅单击“检查”），然后单击“控制台”，然后复制粘贴以下脚本，然后点击return。
Step 3:
第 3 步：
var i = 0;
var myVar = setInterval(myTimer, 3000);
function myTimer () {
var els = document.getElementById("grid-container").getElementsByClassName("ytd-expanded-shelf-contents-renderer");
if (i < els.length) {
els[i].querySelector("[aria-label^='Unsubscribe from']").click();
setTimeout(function () {
var unSubBtn = document.getElementById("confirm-button").click();
}, 2000);
setTimeout(function () {
els[i].parentNode.removeChild(els[i]);
}, 2000);
}
i++;
console.log(i + " unsubscribed by YOGIE");
console.log(els.length + " remaining");
}
Step 4: Sit back and watch the magic!
第 4 步：坐下来观看魔术！
Enjoy!!
享受！！
NOTE:If the script stops somewhere, please refresh the page and follow all four steps again.
注意：如果脚本在某处停止，请刷新页面并再次执行所有四个步骤。

Updating the answer provided by everyone else (as the latest update did not work for me):
更新其他人提供的答案（因为最新的更新对我不起作用）：
var i = 0;
var count = document.querySelectorAll("ytd-channel-renderer:not(.ytd-item-section-renderer)").length;
myTimer();
function myTimer () {
if (count == 0) return;
el = document.querySelector('.ytd-subscribe-button-renderer');
el.click();
setTimeout(function () {
var unSubBtn = document.getElementById("confirm-button").click();
i++;
count--;
console.log(i + " unsubscribed");
console.log(count + " remaining");
setTimeout(function () {
el = document.querySelector("ytd-channel-renderer");
el.parentNode.removeChild(el);
myTimer();
}, 250);
}, 250);
}For me this did the trick.
对我来说，这成功了。

Most effective values:
最有效的值：
(copy all above this, including the last)
（复制以上所有内容，包括最后一个）
var i = 0;
var myVar = setInterval(myTimer, 200);
function myTimer () {
var els = document.getElementById("grid-container").getElementsByClassName("ytd-expanded-shelf-contents-renderer");
if (i < els.length) {
els[i].querySelector('[aria-label="Unsubscribe from this channel."]').click();
setTimeout(function () {

setTimeout(function () {

This is a little addition to the best answer: You can also use jscompress[dot]com to compress the script, then add javascript:at the beginning of the script, and add it to your bookmarks — you can run it from there — just in case you're not comfortable using console or something like that. Good luck! :)
这是对最佳答案的一点补充：您还可以使用 jscompress[dot]com 来压缩脚本，然后在脚本的开头添加javascript:，并将其添加到您的书签中——您可以从那里运行它——只需如果您不习惯使用控制台或类似的东西。祝你好运！:)
P.S I don't have enough rep points to comment, so, no need to tell me something I know I should've done if it were possible.
PS我没有足够的代表点来评论，所以，没有必要告诉我一些我知道如果可能的话我应该做的事情。

Hmm, wish I'd googled before rolling out my own. I had some fun with asyncand awaitwith this. The screen does some ugly flashing while it's trying to unsubscribe stuff, but this does the job pretty well.
嗯，希望我在推出自己的产品之前先用谷歌搜索一下。我async和await这个玩得很开心。屏幕在尝试取消订阅时会出现一些难看的闪烁，但这很好地完成了这项工作。
One prerequisite for this script to catch all channels in one go is to "exhaust" the scroller in the page ie., keep scrolling until you reach the end of your channel list. As others have stated, head on over to YouTube Channels, open the developer console and paste the script that follows.
此脚本一次性捕获所有频道的一个先决条件是“耗尽”页面中的滚动条，即，继续滚动直到到达频道列表的末尾。正如其他人所说，前往YouTube 频道，打开开发者控制台并粘贴以下脚本。
