Finding the smallest number or the highest one is common question that every coder will face. It was easy question. When using JavaScript, there are several method that can help.

For an example, we have an array like this

[34, -345, -1, 100]

As we know the smallest value is -345 and the highest one is 100. To get that value, easily we just need to sort them, so it become like this.

[-345, -1, 34, 100]

After that, we can get the smallest and the highest value by accessing the first index or last index. Or if you want to get shortest path, using the Math method .min() and .max() it will save your time a lot.

Here is my code:

• https://coolors.co/
• https://mycolor.space/
• https://colorhunt.co/
• https://colordrop.io/
• and much more…

Have you ever thought about building a generator by yourself?

In this article, I want to share about how to make your own random color generator using Vanilla JavaScript. The main is finding how to make string that contain hex color number.

After some research, I found some interesting article, we can build the hex color by using combination of Math.random() and Math.floor() feature from JavaScript. There is six digits inside hex color number, every digit has 16 number, between 0 until F. …

Do you still remember, a few years ago, verification method in some site using captcha. Captcha is a type of challenge-response test to check the user is human or robot. In this article, i want to build simple captcha verification method using JavaScript.

Let me tell you again, this perhaps not the brute force hacking tutorial you want to search. This tutorial is just for fun and educational purpose only. Instagram is a great platform, why you still trying to find a password by using brute force. Instead of using it, why not try social engineering attack that more realistic.

This article is just for fun, I don’t want to exploit Instagram, I just want to help you amuse your friend…

Initializing an array is simple concept, but make it into alphabet is different thing. Perhaps for many people this article is useless. But, i’m not seeing anybody write this article yet. So i write this one. The first concept is we need to initialize an array that fulfilled with the number of integer. It can be done using some method just like below.

ES6

Array.from(Array(10).keys())
//=> [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

Spread Operator

[...Array(10).keys()]
//=> [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

map function

Array.from({length: 10}, (_, i) => i + 1) //=> [1, 2, 3, 4…

Bahasa Python adalah bahasa universal, bahasa ini bisa berjalan baik digunakan untuk menyelesaikan beragam operasi mulai dari perhitungan, web development, data science, hingga artificial intelligence.

Pada artikel kali ini saya hendak membahas salah satu kegunaan bahasa python yaitu dalam pembuatan suatu grafik atau lebih umumnya dikenal istilah chart. Tentu diperlukan suatu library untuk dapat membuatnya, library tersebut bernama Matplotlib . Library ini dapat diinstal dengan perintah

pip install matplotlib

Maupun cara lainnya, silakan download source code dari github saya pada bagian bawah artikel ini. Lalu pada direktori yang berisikan file source code ketikkan perintah berikut

pip install -r requirements.txt
