variable

11-GLOBAL variables allow you to access data
2between collections, requests, test scripts,
3and environments. Global variables are
4available throughout a workspace.
5
62-COLLECTION Only accessible within the same collection and
7can not be accessed anywhere else
8COLLECTION variables are available throughout 
9the requests in a collection and are independent
10of environments, so do not change based on the selected environment.
11I use collection variables when
12I use single environment like url details.
13We can refer to the variable by using {{}}(double curly brace)
14and  it can be used anywhere
15
163-ENVIRONMENT Variable , a variable that accessible
17only when the environment is active 
18
19Usually used for an app with multiple environment ,
20we can use env variable to store variable with same name
21and different value to store environment specific data 
22
23for example : 
24
25xxxNamed app has 3 environments with different
26URL and Crendentials 
27
28But all endpoints are exactly the same no matter what
29environment you work on 
30
31so we can create 3 environment called 
32QA1 , QA2 , QA3 and run same set of request 
33by selecting different environment.
34
35Only one environment can be active at a time.
36
37
384-LOCAL variables are temporary, and only
39accessible in your request scripts. 
40Local variable values are scoped to a 
41single request or collection run, and are no longer
42available when the run is complete.
43
44
455-DATA variables come from external CSV and JSON files
46to define data sets you can use when running collections
47via the Collection Runner.

1-- In programing variables exist in 99%(if not all) of programing languages:
2-- Think of them as little boxes that can store data
3-- some examples:
4
5-- C#
6  count = 0;
7  While true
8  {
9    count = count + 1;
10    print(count);
11  }
12  
13-- Python
14	count = 0
15	While True:
16    	count = count + 1
17        print(count)
18        
19-- as you see, both of these programs will output:
201
212
223
234
245
256
267
278
289
29...
30-- and it will keep counting till you crash the program.
31
32-- (ps I am using sql cause it looks nice and hilights a bunch of stuff)
