These are some of the characteristics of JSON:
It uses a hierarchical structure and contains nested values.
It uses braces { } to hold objects and square brackets [ ] hold arrays.
Its data is written as key/value pairs.
No second thought. It's a JSON array. In JSON, an array is an ordered list of values enclosed in square brackets ([]). Each value within the array can be of any valid JSON data type, such as objects, strings, numbers, or other arrays. In this case, the JSON code represents an array containing three objects, each containing key-value pairs.
Each line in the JSON code represents an element (object) within the array. Each object contains key-value pairs, such as "switch": "3750", "port": "e2" in line 2, "router": "2951", "port": "e20" in line 3, and so on.
