Flag implements the command parsing

Encoding/json JSON object that implements encoding and decoding definitions

Html/template data-driven templates for generating text output, such as HTML

The template is associated to the data structure for parsing. The template content points to the elements of the data structure (usually the fields of the structure or the keys of the map) to control the parsing and determine that a value is displayed. The template scans the structure for parsing, and the cursor determines the value in the current location clutter.

Net/http implements HTTP requests, corresponding and URL parsing, and provides extensible HTTP services and basic HTTP clients.

Unsafe unsafe contains all the unsafe operations on the Go program type. By not having to use this.

Reflect implements run-time reflection, allowing the program to manipulate objects through abstract types. By using the value to handle the static type interface{}, and by TypeOf to parse out the dynamic type information, an object with the interface type type is usually returned.
