Las arrow functions son geniales porque hacen que tu código se vea mejor pero cuando estas empezando se vuelve un tanto confuso. Acá un ejemplo de ambas. Tienen el mismo funcionamiento pero sin la algunas palabras reservadas. 
Las arrow functions se pueden pasar como parametros a algunos métodos de arreglos por ejemplo para ordenar un arreglo de números con el método sort. Y queda mucho mas sencilla la sitaxis.
Otro ejemplo con arreglos que queda bastante minimalista es el de elevar todos los elementos dentro de un arreglo al cuadrado. Notesé que no se ocupan las llaves dado que es una única instruccion no son necesarias. #js #javascript

Recently I figure out that the car hailing fleet managers in Romania spend a lot of time with the administration part of their business.
The idea: create a simple app that manage their money, expensive, presenting weekly payment reports for each individual driver

Shamelessly stealing an idea from @jacksonfall and prompting GPT-4 to help me build a profitable business.

Alright so the approach here is to find a product or service with high demand and low supply using a website like @junglescout or @GoogleTrends
On Google trends, the term "chat GPT" is exploding in popularity so I asked HustleGPT to suggest products related to that.

The answer? Chat bot scripts. That sounds easy enough 😅

My learning journey is vast, immersive, and cyclical. If I don't finish something right away, or if I start something new, I almost always cycle back to the old ones. I feel I have learned a lot this way, for better or worse.

💡 Mindset (1/2)
The SaaS space is a mature, highly commoditized one where you can cherry-pick a lot of what is needed from a pool of mature services and ready-to-use modules and use well-established, common best practices.

Just don't lock yourself into short-lived technologies or dependencies.
And let your team only build stuff that sets you apart from the competition and/or builds up real value in your startup.
Buy everything else (the commodities)

F-strings in Python : The ultimate usage tips ⚡
F-strings in Python are a concise and powerful way to format strings. You can include any valid Python expression inside the curly braces in an f-string.

To use an f-string, just prefix your string with the letter "f".

One of major changes in recent @CodeceptJS was removal of allure reporter
I didn't do it for political reasons
It just happened, that Allure reporter v1 was not maintained and Allure v2 has not been released. It took 4 years for team to not release it at all

@CodeceptJS I remember I spent a lot of time integrating Allure in CodeceptJS. I liked the flexibility of API as I could put nested steps into it. However, implementation became very complex (it is always complex for nested steps)
I thought Allure would be a standard of reporters.

For unobvious reasons Allure team stopped development of their JS version and started v2.
Also Allure still required Java to run. Phewww...
It was complicated and was too heavy for a simple HTML report

Javascript Error handling tactics every web developer should know:
1. Try/Catch Statements
This code block tries to execute a section of code, and if an error occurs, it jumps to the catch block to handle the error.
This is very important for handling any runtime faults that may occur.

In javascript, Spread operator allows to mention elements of the items such as array/strings/objects one by one at the required place
Spread behaves just like when we take out playing cards from the box & spread them to play

👩🏫 Spread syntax can be used with
☝️elements that can be iterated/looped such as array or string
☝️objects
Note: the spread syntax loops through the object properties & add the key-value pairs to the new object

👩🏫 Spread syntax is accepted at three distinct places
1⃣ Function call - arguments list
myFunction(a, ...iterableObj, b)
2⃣ Array literals
[1, ...iterableObj, '4', 'five', 6]
3⃣ Object literals
{ ...obj, key: 'value' }

In JavaScript, generator functions are a special type of function that allows you to use the yield keyword to pause and resume the execution of the function.
#100DaysOfCode #NodeJS #CodeLife
#100DaysOfCode #NodeJS #CodeLife
They allow you to create iterators, which are objects that can be used to iterate over a sequence of values.
A generator function is defined using the function* keyword and can be invoked using the yield keyword.

Understand the difference between Javascript "==" and "===" operators:
In JavaScript, "==" is the equality operator and "===" is the strict equality operator.
The main difference between the two is that "==" compares values for equality and performs type coercion if necessary, while "===" compares both values and types for equality.
The main difference between the two is that "==" compares values for equality and performs type coercion if necessary, while "===" compares both values and types for equality.
For example:
If you use "==" to compare the number 5 to the string "5", the comparison will return true because JavaScript will transform the string to a number before performing the comparison.
If you use "==" to compare the number 5 to the string "5", the comparison will return true because JavaScript will transform the string to a number before performing the comparison.
