I am new to JavaScript. I want to print this star pattern using console.log() in JavaScript
*
* *
* * *
* * * *
* * * * *
I tried this code
for(var i=1; i <= 5; i++)
{
for(var j=1; j<=i; j++)
{
console.log('*');
}
}
Each * is getting printed on a separate line.
Kindly help. Thanks :)
I guess this code works
let star = "\n";
for(var i=1; i <= 5; i++)
{
for(var j=1; j<=i; j++)
{
star += '*'
}
star += "\n";
}
console.log(star);
It outputs
"
*
**
***
****

"
for(var i=1; i <= 5; i++)
{
let startStr = '';
for(var j=1; j<=i; j++)
{
startStr += '* '
}
console.log(startStr.trim());
}
I believe that in regular JavaScript there is no way of printing to the console without a trailing newline, so instead, I'd suggest the following code
for(var i=1; i <= 5; i++){
let finalString = ""
for(var j=1; j<=i; j++){
finalString += "* ";
}
console.log(finalString)
}
which saves the lines to a variable before printing them, removing the newline between them. Another option might be
var finalString = ""
for(var i=1; i <= 5; i++)
{
finalString += "* "
console.log(finalString)
}
which doesn't use nested loops but does a similar thing to the previous one, just more efficient.
This is little bit tricky try out this -
use string.repeat function
let star = "*";
for (var i = 1; i <= 5; i++) {
console.log(star.repeat(i));
}
