What is babel used for?

Babel is used to make sure the javascript in your website are all backward compatible. So older engine of javascript can be used to access your website, as well as modern javascript.


What is the difference between babel and package.json?

Babel is considered a library, while package.json is a file that describes the meta data of a project, as well as defining the functional attributes that include the dependencies included and scripts to be ran (for building the dev and production environment). You can use Babel by including Babel dependencies into package.json

Where should I create the .babelrc file?

1) .babelrc file can be created anywhere, preferrably within the same directory of package.json. 

2) You can use babel by specifying the `"babel": {}` within the package.json as well. [source] 

3)  If .babelrc file is not found anywhere, Babel will traverse up the directory to find the .babelrc file, or it finds the `"babel": {}` within the package.json.

Running CQL scripts in Cassandra

How to run CQL scripts in Cassandra  There are 2 ways to run a CQL script, the first way would be running the following command: - cqlsh -f {directory} The second way would be using the command within the CQLSH terminal: - source '{directory}' Where does the {directory} points to? The directory points to the root of your server. For example, if you are on linux, the root would be `/`. Therefore, if you placed your scripts under the folder `scripts`, your directory would look like this `/scripts/{cql_script_name}.cql`.  I've been running the command, but it keeps saying `No such file or directory`? If you met this error, please make sure that:      - The file actually exist in the directory. You can check if by typing `ls -l {directory}`. If it doesn't exist, it will show the same error. If you are on docker, and you are unsure of how to mount your CQL file into your container, you can check out this guide.      - The CQL file has the correct exten...
