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:

newStack().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 constructorletpreInitStack=newStack(1,"2",3,[4,5],6);preInitStack.size;//5//Added elements classically via push()letstack=newStack();stack.size;//0stack.push(1).push("2");stack.size;//2stack.pop();//"2"stack.size;//1stack.peek();//1stack.size;//1
