Question

My background is in java and right now Im getting into learning Javascript. (I’m porting this java code that I made into javascript but it behaves a bit different than I expected?? If I use “console.log()” instead of “document.write” I’m NOT getting the same result..why?

thanks 4 yr time! Some insight will be very appreciated!

var counter = 1;    

function println(str) {

    console.log(str);//

}   

for (var i = 1; i <= 5; i++) {

  for (var j = i; j < 5; j++) {

       document.write("#");
// println("#"); 


  }

  for (var k = 1; k <= counter; k++) {

    document.write("*");
// println("*"); 

  }

  document.write("<br/>");
//println(" "); <--- "\n" ? 

  counter+= 2; //
} // ends application

Answer 1

document.write() is for printing content to the page of your document, while console.log() is used predominantly for diagnostic/debug information to be emitted in the console of your web browser. Specifically, document.write() is intended to be consumed by the viewer of your page, while console.log() is generally not.
