Is React-Native the best choice for mobile app development?

Here’s a controversial question about React-Native: Is React-Native the best choice for mobile app development, or are native mobile app development platforms (such as Android’s Java and Kotlin or iOS’s Swift) a better choice in the long run? This is a controversial topic because there are strong arguments to be made for both sides. Some people argue that native mobile app development platforms offer the best performance and user experience, while others argue that React-Native’s cross-platform capabilities and faster development cycle make it the better choice in most cases. What do you think?

It’s difficult to give a definitive answer to this question, as the best choice will depend on the specific needs and goals of the project. Here are some pros and cons of each approach to consider:

Native mobile app development:

Pros:

  • Typically offers the best performance and user experience, as the app is developed specifically for a particular platform
  • Can take advantage of all the features and capabilities of the target platform
  • May have better long-term support from the platform vendor

Cons:

  • Requires separate development teams for each platform (iOS, Android, etc.), which can be costly and time-consuming
  • Slower development cycle, as code must be written and tested separately for each platform

React-Native:

Pros:

  • Allows for cross-platform development, meaning a single codebase can be used to build apps for multiple platforms
  • Typically has a faster development cycle, as code can be shared across platforms
  • Can be a more cost-effective option, as a single team can develop an app for multiple platforms

Cons:

  • May not offer the same level of performance as a natively developed app
  • May not have access to all the features and capabilities of the target platform
  • Long-term support may not be as reliable, as the platform is not backed by a major tech company like Apple or Google

Ultimately, the best choice will depend on the specific needs and goals of the project, as well as the resources and expertise available to the development team.

Remove Array Duplicates in ES6

const array = ['🐑', 1,  2, '🐑','🐑', 3];

// 1: "Set"
[...new Set(array)];

// 2: "Filter"
array.filter((item, index) => array.indexOf(item) === index);

// 3: "Reduce"
array.reduce((unique, item) => 
  unique.includes(item) ? unique : [...unique, item], []);


// RESULT:
// ['🐑', 1, 2, 3];

How to remove a big file wrongly committed

I added a large file to a git repository (102Mb), commited and push and got an error due to size limit limitations on github

remote: error: GH001: Large files detected. You may want to try Git Large File Storage - https://git-lfs.github.com. 
remote: error: Trace: 7d51855d4f834a90c5a5a526e93d2668 
remote: error: See http://git.io/iEPt8g for more information. 
remote: error: File coverage/sensitivity/simulated.bed is 102.00 MB; this exceeds GitHub's file size limit of 100.00 MB

Here, you see the path of the file (coverage/sensitivity/simualted.bed). 

So, the solution is actually quite simple (when you know it): you can use the filter-branch command as follows:

git filter-branch --tree-filter 'rm -rf path/to/your/file' HEAD git push
