Is there anyway to console.log without a newline?

Question

I want to console.log() my array like this without newlines

let myarr = [1,2,3,4,5];
myarr.forEach(e => console.log(e));

Does this answer your question?

You could spread the array. Then all values are taken as parameters.

let array = [1, 2, 3, 4, 5];

console.log(...array);

You can use .reduce() instead.

let myarr = [1,2,3,4,5];
const result = myarr.reduce((a, c) => `${a}${c}`, '');
console.log(result);

I hope this helps!

Why are you doing a separate console.log for every element in the array? You can just do:

console.log(myarr);

Or, if your array has objects in it and you want to see them all unrolled, you could do:

console.log(JSON.stringify(myarr));

You would have to stringify your output.

So either using something like JSON.stringify(myarr) or

let string = '';
for(let i = 1; i < 6; i += 1) {
  string += i + ' ';
}
console.log(string);

Edit: Btw, I'd suggest using camelCase when working with javascript. It's become a standard when defining variables and methods.
