How can I customize a suffix snippet, replacing the variable in VS Code?

I'm developing my Java project with VS Code when I find some powerful snippets:

suffix code snippets

After I type a variable name and type .sysout, .cast and so on, the snippet suggestion pop out. When inserting, it leads to:

res.sysout => System.out.println(res);

res.cast => (()(res))

...

I'm curious about how to realize this feature in my VS Code. By the time, I didn't find anything useful at redhat-developer/vscode-java.

Then I want to transplant the snippet to support JS/TS, and other languages.

I detailedly read VS Code's doc about snippets, find something that might be useful:

The following variables can be used:

  • TM_SELECTED_TEXT The currently selected text or the empty string
  • TM_CURRENT_LINE The contents of the current line
  • ...

However, when I try to create the snippet, I don't know how to replace the variable name. In other words, I can get the variable name by TM_CURRENT_LINE, insert a snippet, but the previous variable name remains. For instance,

res.log => resconsole.log(res);

This feature is called post-fix completion: https://code.visualstudio.com/docs/java/java-editing#_postfix-snippet-shortcuts

For TS/JS, there are some extensions support that, for example:
