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
