Import an operator to be extended in Julia - module

I was trying to define:
.*(s1::String, s2::String) = string(s1,s2)
and got an error: function Base..* must be explicitly imported, so I did:
import Base..*
but got another error: invalid operator "..*".
How should I import this operator?

You can do
import Base.(.*)
What is the use case?

BigQueryCheckAsyncOperator in airflow does not exist

I am trying to use async operators for bigquery; however,
from airflow.providers.google.cloud.operators.bigquery import BigQueryCheckAsyncOperator
gives the error:
ImportError: cannot import name 'BigQueryCheckOperatorAsync' from 'airflow.providers.google.cloud.operators.bigquery'
The documentation in https://airflow.apache.org/docs/apache-airflow-providers-google/stable/operators/cloud/bigquery.html mentions that BigQueryCheckAsyncOperator exists.
I am using airflow 2.4.
How to import it?
The operator you are trying to import was never released.
It was added in PR and removed in PR both were part of Google provider 8.4.0 release thus overall the BigQueryCheckAsyncOperator class was never part of the release.
You can use defer mode in the existed class BigQueryCheckOperator by setting the deferrable parameter to True.

I am trying to access my table in SQL database. However, I am getting an unusual error. Can someone please help me I am very new at this.
import sqlite3
import pandas as pd
com = sqlite3.connect('Reporting.db')
Note: Panda dataframe is already defined above that's why I am not including this over here.

Note #2: I am using Anaconda Navigator for writing scripts
Solved it!! that's my Syntax
import sqlite3
import pandas as pd
com = sqlite3.connect('Reporting.db')
df.to_sql('tblReporting', com, index=False, if_exists='replace')
print('tblReporting loaded \n')
org_query = '''SELECT * FROM tblReporting'''
df = pd.read_sql_query(org_query, com)
df.head()
Note: added ''' before and after my org_query helped me resolved this

CoffeeScript2: SyntaxError: Cannot use import statement outside a module

I'm working on a express server. I can develop faster using CoffeeScript2 ("write less do more").
The code
import { Sequelize, Model, DataTypes } from 'sequelize'
gives me the error:
SyntaxError: Cannot use import statement outside a module
I guess I have to use babel? How can I set it up?

How to import ErrorUtils in React Native

RN version: 0.50
Testing on Android, haven't tested on iOS
I am trying to use ErrorUtils.setGlobalHandler as described in this github issue: https://github.com/facebook/react-native/issues/1194
However, what is not clear from the issue is how to import ErrorUtils. It's not in the react documentation: https://facebook.github.io/react-native/docs/0.50/getting-started.html
Previously, in RN 0.41, I was able to import ErrorUtils with import ErrorUtils from "ErrorUtils"; However, in 0.50 I am getting a red react popup with the following message when I try to import ErrorUtils like this:
com.facebook.react.common.JavascriptException: Failed to execute 'importScripts' on 'WorkerGlobalScope': The script at 'http://localhost:8081/index.bundle?platform=android&dev=true&minify=false' failed to load.
I've also tried import { ErrorUtils } from 'react-native'; but it doesn't seem to exist there. The error is:
Cannot read property 'setGlobalHandler' of undefined
How do I properly import ErrorUtils in RN 0.50?
ErrorUtils is a global variable, therfore it doesn't need to be imported. You can verify this with console.log(global.ErrorUtils)
However it is exported as module anyways (here). The comment there also has more information why it is done this way.
You can import the module like this:
import ErrorUtils from 'ErrorUtils';
For anyone on RN61+, you should no longer import the module as you will experience the following error in the running metro bundler:
Error: Unable to resolve module `ErrorUtils`
Instead, just use the module without importing as this is a global variable, as stated by leo
I did created a global.d.ts to define a global variable,
interface Global {
ErrorUtils: {
setGlobalHandler: any
reportFatalError: any
getGlobalHandler: any
}
}
declare var global: Global
then, at where you are trying to use it, simply
global.ErrorUtils.setGlobalHandler(xxxx)

Substring on jmeter variable in beanshell script error

Using jmeter, I have a variable that is obtained by xpath expression. I have then used beanshell post processor to then get a substring (last 4 characters) which will be used in another request.
However, I keep getting an method invocation error for the script below.
import org.apache.jmeter.util.JMeterUtils;
import java.lang.*;
import java.io.*;
String numb = String.valueOf(vars.get("num"));
String last4 = num.Substring(num.length()-4, num.length());
log.info("num");
Any ideas as to what I'm doing wrong?
Added the correct libraries, which is as follows:
import org.apache.jmeter.util.JMeterUtils;
import org.apache.commons.lang3;
Change the start and end index values as well
