Create a Wallet function that can be called multiple times & maintain balance and transactions, we should be able to call it in a chain way. example is 👇
Wallet(); // prints nothing or its up to you whatever you want to print.
Wallet().getBalance(); // Balance is 0.
Wallet().add(50).add(70).getBalance(); // Added 50. Added 70. Balance is 120.
Wallet().showTransactions(); // +50 <<Date time>>. +70 <<Date time>>.

In a JavaScript method, the value of this has nothing to do with the class on which it was defined. Instead, it depends on the object that it was called upon.
import React from "react";
import ReactDOM from "react-dom";
class App extends React.Component {
render() {
var { handleClick } = this;
| <html> | |
| <head> | |
| <title>Parcel Sandbox</title> | |
| <meta charset="UTF-8" /> | |
| <script> | |
| function isValidEmailId(emailId) { | |
| var exp = /^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/ | |
| return exp.test(emailId) | |
| } |
Ever wondered why setting array.length = 0 makes an array empty or array.length = 'some string' throws exception ?
Code example.
So now you have curiosity to know what happens in the background when command array.length = 0 takes place ?
Let's start this journey with below requirement.
Create a higher order function that accepts a react component. Do logs when life cycle methods (componentWillReceiveProps or render) are called
F1.js
export function hocF (Component) {
const cwp = Component.prototype.componentWillReceiveProps;
Component.prototype.componentWillReceiveProps = function(...args) {
console.log('in Component will receive props....')
cwp.call(this, ...args)
}
