ReScript Project Template

The rescript-immutable-js package provides ReScript bindings for the Immutable.js library.

Usage Examples

ImmutableList

open ImmutableList

// Create a new list
let myList = make([1, 2, 3])

// Add elements to the list
let updatedList = myList->push(4)->pushN(5, 6)

// Concatenate lists
let anotherList = make([6, 7, 8])
let combinedList = updatedList->concat(anotherList)

// Access elements
let thirdElement = combinedList.get(2)

// Filter elements
let evenNumbers = combinedList.filter(num => num mod 2 == 0)

// Convert to array
let arrayResult = evenNumbers.toArray()

ImmutableMap

open ImmutableMap

// Create a new map
let myMap = make({
   key1: "value1",
   key2: "value2"
})

// Set a new key-value pair
let updatedMap = myMap->set("key3", "value3")

// Get a value
let value = updatedMap.get("key2")

// Map over key-value pairs
let upperCaseMap = updatedMap->map((k, v) => v->Js.String2.toUpperCase)

// Convert to object
let objResult = upperCaseMap.toObject()
