Examples of JSON statements
JavaScript Object Notation (JSON) is a key-value format for representing structured data. It is
text-based, which makes it readable. There are a few things to know about its syntax.
Defining strings
Use double quotation marks around strings.
Examples:
1
{"name":"John"}
2
{"age":30}
3
{"sale":true}
1
meaningful_variable_name = {
2
"employee":{"name":"John", "age":30, "city":"Montreal"}
3
}
Access the value John by writing
${meaningful_variable_name.employee.name}
Define a variable named
var
as an array of values.
1
{"n":[0,1,2,3,4,5]}
The result of
${var.n[0]}
is 0 and of
${var.n[3]}
is 3.
Defining iterators
When you define a variable as an iterator, it must be defined as type Number. The first index is
always 0.
${var.n[${i}]}
outputs the value of each iteration over the array.
