Modifying state for specific item in array in redux reducer

Asked 2019-Dec-26 at 13:49

I can't quite wrap my head around the boilerplate of redux. I looked up common patterns for immutable modifying of state but issue is, all these patterns simply push towards the end and not for a specific index.

Before I'll go into actual code, here's what the structure of the state looks like for better imagination (pseudo-code):

the push method of Array returns the new length of the array not the array itself. What you can do is just concat the new object to the array which in turn will return the new array with the new question option.

function executes before and result doesnt applies

Asked 2018-Oct-04 at 07:53

Im doing better with my project but im still trying to figure out about some things that are not working properly. For example, i created a button "UTG1" which filters in green a specific range from the matrix. When this button is clicked, only the values that doesnt has GREEN background should be deleted but it happens that all the values are deleted first and then the background is set. Any clue about this? Thanks in advance!

With that being said, it's an old Mozilla file from an old install which has since been removed and while I'd like to just delete it, I'd also like to try to decipher what it means first.

Any ideas or suggestions?

An XPI file is just a ZIP file with a different extension.

Simply rename the file and unzip, or use 7-zip to unzip the content (you won't have to rename the file using 7-zip).

The XPI is used to pack extensions for Firefox/Thunderbird and indicates that the content is signed. The content will vary depending on what type the extension is, but it will contain a manifest.json file. Any programming language will be in JavaScript which may reside in root and/or in various folders.

Install aqo

The module works with PostgreSQL 9.6 and above. To avoid compatibility issues, the following branches in the git-repository are allocated:. The module contains a patch and an extension. Patch has to be applied to the sources of PostgresSQL. Patch affects header files, that is why PostgreSQL must be rebuilt completely after applying the patch (make clean and make install). Extension has to be unpacked into contrib directory and then to be compiled and installed with make install. Tag version at the patch name corresponds to suitable PostgreSQL release. For PostgreSQL 9.6 use the 'aqo_pg9_6.patch' file; PostgreSQL 10 use aqo_pg10.patch; for PostgreSQL 11 use aqo_pg11.patch and so on. Also, you can see git tags at the master branch for more accurate definition of suitable PostgreSQL version. It is essential that library is preloaded during server startup, because adaptive query optimization must be enabled on per-cluster basis instead of per-database.
stable9_6.
stable11 - for PG v10 and v11.
stable12 - for PG v12.
the master branch of the AQO repository correctly works with PGv13 and the PostgreSQL master branch.
