JS Canvas shape duplication issues

He guys, I just bumped into this issue while creating a drawing app. I started with stroke rectangle shapes, it works fine in some places inside the canvas but when it reached around 50% to the right of the canvas it keeps printing. I really appreciate if someone can help point what is wrong with this code thank you! video: https://www.loom.com/share/958daa9f8db643e59f1b987061886128 code: https://codepen.io/jtzuya/pen/eYoweNa?editors=1111

is it possible to throw your local variable out to globally so that you can reuse it?

e.g.

 
let x = 'a random string'

function test() {
  let y = 'bzzz'
  return y
}

 
let x = 'a random string'

function test() {
  let y = 'bzzz'
  return y
}

I want to use the 'y' variable globally, is that possible?

using Regex in an if else statement

hey guys, I created and logical statement with regex init but doesn't seem to work

let operation = Math.floor((Math.random() * name.length - 1))
    if(name[operation] === /\s$/g || name[operation] === undefined) return mathChallenge(name)

let operation = Math.floor((Math.random() * name.length - 1))
    if(name[operation] === /\s$/g || name[operation] === undefined) return mathChallenge(name)

so basically on my statement, instead of using " ", I used regex of space. I wonder if using regex is executable and if so, how should it supposed to be

Webpack output to the wrong directory

Hey guys, I have a quick question. I've got this webpack setup

const path = require('path')

module.exports = {
    "mode": "development",
    entry: {
        main: './src/module.js'
    },
    module: {
        rules: [
            {
                test: /\.css$/,
                use: ['style-loader', 'css-loader'],
            },
        ]
    },
    output: {
        filename: '[name].js',
        path: path.resolve(__dirname, '/assets')
    }
}

const path = require('path')

module.exports = {
    "mode": "development",
    entry: {
        main: './src/module.js'
    },
    module: {
        rules: [
            {
                test: /\.css$/,
                use: ['style-loader', 'css-loader'],
            },
        ]
    },
    output: {
        filename: '[name].js',
        path: path.resolve(__dirname, '/assets')
    }
}

And I would like to compile my output in the 'assets' folder but when I run npm start it rather compile to the wrong directory

'/public' directory
asset main.js

'/public' directory
asset main.js

output after compiling. I'd want it to be compiled here

'/assets' directory

'/assets' directory

Thanks for the answers🙌🏼

About Array lengths

Hi guys I have a question, let's say I got an array. Then I will execute an if statement saying

if(!array.length) return

if(!array.length) return

Now the question, does mean that the arrays length is equal to 0... or null? And is it different if I say

if(array.length === 0) return

if(array.length === 0) return

Thanks 🙌🏼
