How do I deploy an updates project and publish on github? - reactjs

Question

The issues I am having the past few days is that I can not update my 
https://filipzafran.github.io/Best-TO-DO-App-in-the-history-of-the-universe/  website page.
Although the gh-pages branch is updated with the new code, it still shows the old one.
I have:
 - deleted and created again the gh-pages
 - pushed a new commit 
 - re-merged with master
 - cleared browser history (catche)
 - read numerous solutions
Still cant make it publish the new code on my gh-pages website.
I feel like there might have to do with depolyment.
Do I need to deploy again?
Because when I do, from master, it gives me a long error:
redux-todo-step_by_step git:(master) npm deploy
Usage: npm <command>
where <command> is one of:

Assuming you have a deploy script in your package.json, to successfully execute it you have to type in npm run deploy as deploy isn't an npm command per se.
In npm, run is the command that allows you to execute your custom scripts.
Here's an example of a package.json and relative commands...
{
"name": "raci-api",
"version": "0.4.0",
"description": "raci API",
"main": "src/server.js",
"scripts": {
"start:dev": "nodemon src/server.js -e \"NODE_END=development\"",
"start:production": "node src/server.js -e \"NODE_ENV=production\"",
"lint": "eslint src/**/*.js",
"lint:fix": "eslint --fix src/**/*.js",
"docs:serve": "npx http-server -c-1 docs -o",
},
"author": "",
"license": "ISC",
"repository": {
"type": "git",
"url": "yourRepoURL"
},
"dependencies": {
"yourDependencies": "here"
},
"devDependencies": {
"yourDevDependencies": "here"
}
}
In this case, to properly serve the app (E.G. in loopback) you have to use npm run start:dev.
