stack-data v1.2.0

stack-data

Simple stack implementation on ES6

Install

npm install --save stack-data

Usage

2 ways for adding element in stack:

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

Also supports chaining mechanism like:

 new Stack()
 .push(1)
 .push(2)
 .push(3)
 .push(4)
 
 // creates object with 4 elements 1,2,3,4

// Examples of using stack-data

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

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