Loop

Question

Let's say I have
for(i=1 ; i<8;i++){
Var txt="#"
}

How do I create a loop where the next value for i have an extra #.
Like I should have
#
##
###
#### and so on , where # keeps increasing with i.

Answer 1

Perhaps this might do
Namit Jain Timmy Afolami

In the Js

let amount = 1
let lines = 10
let character = "#"
let toCon;

//Does the loop that is inside the given amount of times

for(i=0; i<lines; ++i){

//Sets toCon back to nothing
toCon=" ";
for(j=0; j<amount; ++j){
toCon+= character //makes one string
}
console.log(toCon) //prints the string

amount++
}

The power of nested for loops comes to the rescue once more👏🏻

Answer 2

Try this:

for (let i = 0; i < 10; i++) {
for (let j = 0; j < i; j++) {
document.write("# ");
}
document.write("<br>");
}

Answer 3

Sorry, my first answer was wrong😅 Timmy Afolami
This should work

In the Js

let amount = 1
let lines = 10
let character = "#"

//Does the loop that is inside the given amount of times

for(i=0; i<lines; ++i){

//Writes the character amount number of times

for(j=0; j<amount; ++j){
document.write(character)
}

document.write("<br/>") // inserts a new line
amount++
}

Good luck on your coding adventure!☕

Vachila64☕ Ooo nicee 😍😍👌👌
I just forgot that we can declare a variable 😅😆

Answer 5

Namit Jain 😅😅😅

Answer 6

I think you should declare a variable to be # at the beginning

Answer 7

Hi, sorry I took some time to get back to you😅. Nested loops are loops that have loops inside loops
The outside loop does the inside loop over and over again. This is useful when you want to do a loop for a particular thing over and over again

I think our will find these helpful as well!
If you still don't understand, I'll be happy to explain more!🙂

Nested Loops JavaScript - Coding Rooms The most common type of nested loops will be one loop inside another. The first loop is usually called the outer loop while the second loop is called the inner loop. The outer loop always executes first, and the inner loop executes inside the outer loop each time the outer loop executes once.

Answer 8

Try this bro

for (var i=0; i<100; i++){
console.log('#'); // Always prints in a line. }

Answer 9

Timmy Afolami actually I don't know how to prevent that line break with every statement 😅

Thanks a lot.
It worked.

Can I also achieve this with console.log ?

Answer 18

You can use 'repeat'

var x = "#"
for (int i = 1; i < 8; i++){
console.log(x.repeat(i))
}
