Remove "the space" in the console.log?

Do think you that it possible to remove the space in the console.log ?

For example on this code

for(var i=0; i<3 ; i++){
    console.log("-");
}

I would like to display my dashes on a line.

I am not sure, if it is very important situation for you, you may write that way in case:

let str = '';
let x = 3;
let i = 0;
while(i<x){
  str+='-';
  if(str.length===x){
    console.log(str);
  }
  i++;
}

But I would not recommend to type such inefficient way just for displaying in console. If you want to test inline console, use node.js with stdin and stdout.

If you log within the loop, then you are issuing multiple console.log() commands and each will be on its own line.

If you record the value and concatenate that to a string, then you can log after the loop with one command.

let result = "";
for(var i=0; i<3 ; i++){
  result += "-";
}

console.log(result);

No. The console is meant for output debugging only, and how it's presented is handled by the debugging tools. At best you can do this:

const line = [];
for(var i=0; i<3 ; i++){
  line.push('-');
}

console.log(line.join(''));
