2.1 Looping a triangle (Eloquent JavaScript Solutions)

2-1 Eloquent Javascript Solutions.js

for (var triangle = "#"; triangle.length <= 7; triangle += "#") 
  console.log(triangle);

In the spirit of “there’s no such thing as a stupid question”

Why does the one below work:

for ( var triangle = “#”; triangle.length <=7; triangle += “#”)
console.log(triangle);

When the next one doesn’t? I transferred the for loop into a while loop and expected the outcome to be the same. But instead of starting at 1 # it starts at 2.

let triangle = “#”;
while (triangle.length <=7) {
triangle += “#”;
console.log(triangle);
}

This is my first outing into JavaScript and I’m starting to think it isn’t for me.

Hey @worgraeme - this stuff can be tricky so keep going!
It's because you initialised triangle with a value of # so it already has one hash in it. Then you added another hash in the while loop before logging to the console where you see two #s
To fix this, initialise triangle with an empty string:
let triangle = "";

Thank you so much for your help. That is shockingly simple.

trying to create one that takes any value and creates a triangle

const loopTriangle = (loopCounter)=>{
let num=' ';
for (let i = 0;i<loopCounter;i++){
num +=" #";

console.log(num);
}
};
if you run the function it will create your desired triangle

//loopTriangle(10)
