Go language tutorial manual

Course Elementary 27446

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.

JavaScript - Remove duplicates from an array and return an array containing the duplicates and another array containing all other items

I want to run a filter or reduce operation on an array and remove all duplicates in the array based on the 'name' attribute like in this example. The examples I've seen are iterating through the array and keeping one of the duplicates, but in my case I need to separate them and return the duplicates to the user in an array to correct the data, and process the other remaining items. I've given an example array and expected result array below. If anyone could give me an example of how to do this I would be very grateful! Thanks! constcustomers=[{id:1,name:

MySQL deduplication, why can only a few hundred or dozens of duplicate data be removed each time, when there are obviously hundreds of thousands of duplicate data?

Requirement: Delete the items with the same primaryid and drugname in DRUG, and keep the smallest row of drug_seq. Question: MySQL uses these methods to remove duplicates.
