document.write() VS console.log()

Question

While browsing through some other Javascript material, I saw console.log() used instead of the regular document.write() used here in Sololearn.

Please in case are they applicable or can they be used interchangeably?

Answer 1

document.write() is for modifying HTML content, and console.log() is for outputtibg to the console.

Answer 2

Okay. I get it now. In that case, I think it's preferable to output to the console instead since it won't affect the markup. Document.write() might unintentionally wipe up existing HTML content.
