json.array Synchronous

Mark a new table as a JSON array, especially when the array may be empty. The marker prevents an empty list from turning into {} when it is encoded.

Syntax

Luau

json.array(source: Table?) -> Table

Parameters

Function parameters
Parameter	Type	Description
`source`	`Table?`	Optional table whose sequence entries, 1 through #source, are copied into the marked result.

Table

A new marked array. Named keys are left out, and nested values are shared rather than deeply copied.

Use json.object for a record with named fields. The array marker remains with this table as items are added.

Luau

local tags = json.array()
print(json.encode(tags)) -- []
table.insert(tags, "featured")
print(json.encode(tags)) -- ["featured"]
