=={{header|Forth}}==

Forth has no built-in higher level data structures such as arrays,

dynamically resizeable arrays, strings, dynamically resizeable

strings, and objects. There is no standardized Forth library to build

and use such structures. But there are many different Forth libraries,

written by individuals, available. Though finding them is not always easy.

The syntax and behavior is different for each.

The library code used below can be found here:

Load a JSON string into a data structure.

<pre>

s\" {\"value\":10,\"flag\":false,\"array\":[1,2,3]}" $>json value j

j :.

</pre>

Prints a JSON as follows:

{

"value": 10,

"flag": false,

"array": [ 1, 2, 3]

}

Create a new data structure and serialize it into JSON.

<pre>

j{ "another":"esc\"aped" }j 1 j :insert

j :.

</pre>

Prints the modified JSON:

{

"value": 10,

"another": "esc"aped",

"flag": false,

"array": [ 1, 2, 3]

}

Convert the JSON object into a string. Print the string.

<pre>

j json>$ :.

</pre>

{\"value\":10,\"another\":\"esc\"aped\",\"flag\":false,\"array\":[1,2,3]}
