stack-data

Simple object stack implementation on ES6

It is based on stack-data, with the added capability to work as a hash

Install

npm install --save stack-object

Usage

2 ways for adding element in stack:

• in constructor new Stack({ "foo": 1},{"2":3},{"bar":[3,[4, 5],6]);
• via push(elem) method

// Examples of using stack-data

//Added stack elements in constructor
let preInitStack = new Stack({ "foo": 1},{"2":3},{"bar":[3,[4, 5],6]);
preInitStack.size;       //5

//Added elements classically via push()
let stack = new Stack();
stack.size;              //0
stack.push(1).push({ "yahoo": "2"} );
stack.size;              //2
stack.pop();             //"2"
stack.size;              //1
stack.peek();            //1
stack.size;              //1
