This proves slices.Delete is the fastest method on x86-64 by CPU instruction count.

All methods usually report 0 nanoseconds when running these tests using time, that is why it tests by using CPU instruction count.

delete without order preserved
	 22 CPU instructions (speed)
delete using append with order preserved
	 1508 CPU instructions (speed)
delete using slices.Delete with order preserved

Importing net/http/pprof adds HTTP endpoints to an existing HTTP or HTTPS server to serve profile files that can be viewed or charted with a command line tool.

import pprof into the go program

import _ "net/http/pprof"

If your application is not already running an http or https server, add "net/http" to the program imports and the following code to your main function:

go http.ListenAndServe(":8550", nil)

ECMAScript modules sometimes known as ES modules

These use the module loader system in the Browser.

When a module is loaded, it has a special name that is only available within this module loader system. The special name is why import doesn't work with modules that import other modules using that special name, because import() cannot assign that name.

Loading is possible with:

import is capable of loading the module's script and setting the special name of the module. This allows other modules to access it. It is not capable of load or error events or a retry function or subresource integrity.
import() is capable of a Promise but it does not allow access to the special name of the module and does not have subresource integrity.
