How to configure emmet? in vscode

now when you write jsx syntax, you always have to manually fill it with

< / div >. How can you write div+tab?
I found the configuration file to make it look like this,

"emmet.includeLanguages": {
    "javascript": "javascriptreact"
}

but I don"t know where to match,

how do you write it when you get to this page?

I just saw JSX.
General

"emmet.includeLanguages": {
    "javascript": "javascriptreact"
},

Just

, just copy it directly to the user settings on the right. (if you move your mouse over in the left setting, there will be a copy button)
