The Stack Class in Javascript
Here is the complete implementation of the Stack class −
Example
class Stack { constructor(maxSize) { // Set default max size if not provided if (isNaN(maxSize)) { maxSize = 10; } this.maxSize = maxSize; // Init an array that'll contain the stack values. this.container = []; } display() { console.log(this.container); } isEmpty() { return this.container.length === 0; } isFull() { return this.container.length >= this.maxSize; } push(element) { // Check if stack is full if (this.isFull()) { console.log("Stack Overflow!") return; } this.container.push(element) } pop() { // Check if empty if (this.isEmpty()) { console.log("Stack Underflow!") return; } this.container.pop() } peek() { if (isEmpty()) { console.log("Stack Underflow!"); return; } return this.container[this.container.length - 1]; } clear() { this.container = []; } }
