Problem background

When using vscode to automatically save, it is found that there is a problem with each save format.

Solution:

There are only a few storage formats

The saving format of vscode itself uses the saving format configured by eslint
so after analysis, the problem is clear at a glance.

After investigation,
it was originally set in vscode settings.json

"editor.formatOnSave": true,

Also set

"editor.codeActionsOnSave": {
   "source.fixAll.eslint": true
},

In this way, the first save takes effect, but the second save uses other configurations, resulting in inconsistency between the two
handle

"editor.formatOnSave": true,

Just delete this configuration. When saving, you can only format it according to the eslint configuration.
