npm workflow automatically deprecate and publish
Automatically publish new version & deprecate the former npm package version
Written in front, if you have the following troubles like me, you need to modify the version in package.json or manually execute npm patch&npm publish every time you publish a new npm package version. And because there are too many release versions when managing your npm packages, and because of some obsessive-compulsive reasons, you want to make the package list more concise, then this article will solve your ...

Some advice:
Make a backup! Make a backup! Make a backup!
It is recommended to copy a copy of the hexo directory source folder for some magic changes and experimental functions to be added for experimentation.
You can use git backup, you can also take the simplest zip backup
The initial backup is recommended to be established based on basic availability
Create a modify.md file to record your modification records

1^2+2^2+···+n^2 Calculation and deduction of stepped area
1^2+2^2+···+n^2阶梯型面积计算推演
The main purpose is to test the work condition of katex rendering.
(n+1)3=(n2+2n+1)⋅(n+1)=n3+2n2+n+n2+2n+1=n3+3n2+3n+1\begin{aligned}
(n+1)^3 &= (n^2+2n+1) \cdot (n+1)\\ &=n^3+2n^2+n+n^2+2n+1\\
&=n^3+3n^2+3n+1
\end{aligned}
(n+1)3=(n2+2n+1)⋅(n+1)=n3+2n2+n+n2+2n+1=n3+3n2+3n+1
(n+1)3−n3=3n3+3n+1(2)(n+1)^3-n^3=3n^3+3n+1
\tag{2}
(n+1)3−n3=3n3+3n+1(2)
n3−(n−1)3=n3−[(n−1)2(n−1)]=n3−[(n2−2n+1)(n−1)]=n3−[n3−2n2+n−(n2−2n+1)]=n3−[n3−2n2+n−n2+2n−1]=n3−[n3−3n2+3n ...
