I recently konw about the word “hard code” and “fusion code“.After searching something in stackoverflow I konw what “hard code” mean.But I don’t quite understand what “fusion code” mean.
Does the terminology means a design mode? Or It’s just a coding way to finish the work efficiently?
More examples would be easier for me to understand!
Thank you!

Well,It’s quite upsetting after I opening Google,typing the keyword “fusion code” and found nothing except some sites sell courses! So this is why I ask this question ,I really want to konw what “fusion code” mean.
If you’re convinent to answer my question or give me any tips ,I’ll be grateful to you.
Thank you!
