Use theArray.reduce()method to iterate over the array. Initialize the accumulator variable to an emptyMap. Add each key-value pair to the newMapobject. index.js constarr=[{key:'name',value:'bobby hadz'},{key:'c
Use theforEach()method on the array to iterate through all the objects. During each iteration, utilize theMap.set()method to add the key-value pair to the map. constusers=[{name:'John Doe',role:'Admin'},{name:'Alex Hales',role:'Manager'},{name:'Ali Feroz',role:'User'}]constmap...

The LinkedHashMap Class is an one type of Hash Map which enables an user to maintain a systematic cronology of the elements present into it. This feature also provides the method of insertion, search and deletion in a quick manner. When we need to convert an array list to a linked hash...
1. ConvertMaptoArray For demo purposes, let us create aMapwithStringkeys andIntegervalues. Map<String,Integer>map=Map.of("A",1,"B",2,"C",3); TheMap.values()returns a collection view of the values contained in this map.UseCollection.toArray()to get the array from collection elements....

Convert the Map to an array. Use the Array.map() method to iterate over the array. Return an object containing the key-value pair on each iteration. index.js const map = new Map(); map.set('name', 'Bob'); map.set('country', 'Chile'); // 👇️ [['name', 'Bob'], ['co...
