6 Differences Every JavaScript Developer Should Know

JavaScript has a lot of functions and reserved words that sound and perform similar actions and many developers use these terms interchangeably without knowing the vital differences between them.

It is not entirely their fault though since JavaScript keeps introducing better ways to perform actions, but for the sake of backward compatibility instead of removing the pre-existing functions that perform the same thing, they tend to add the new ones alongside the old functions.

Before 2015, there was only one way to declare variables and that was with the keyword var . There was no let or const .

Interviewers are keen to know if the candidates are up-to-date with these latest advancements to test how fresh and deep is the candidate’s knowledge and his/her grasp on JavaScipt terms that perform similar actions.

Below are 6 differences you should know for your next technical interview.

1. let vs var

Both let and var are keywords that are used when declaring variables. While both var and let are used for variable declaration in JavaScript but differences exist.

JavaScript had support for let only since 2015 with the release of the version ES6, whereas var was present before and was the only way to declare a variable before let came along.

Another difference is the variable scope, that is, which parts of your program can access and use it. While var is function scoped, let uses block scoping.

For a much better understanding, I will share a relevant example.

var a=10;
function myFun(){
for (var i = 0; i < 2; i++) {     
console.log(`Inside the loop: ${i}`); 
} 
console.log(`Outside the loop: ${i}`);
}
myFun();
console.log(i)

The output of the following would be:

Inside the loop: 0

Inside the loop: 1
Outside the loop: 2
error: Uncaught ReferenceError: i is not define

How long does it take to develop/build an app?

With more of us using smartphones, the popularity of mobile applications has exploded. In the digital era, the number of people looking for products and services online is growing rapidly. Smartphone owners look for mobile applications that give them quick access to companies’ products and services. As a result, mobile apps provide customers with a lot of benefits in just one device.

Likewise, companies use mobile apps to increase customer loyalty and improve their services. Mobile Developers are in high demand as companies use apps not only to create brand awareness but also to gather information. For that reason, mobile apps are used as tools to collect valuable data from customers to help companies improve their offer.

There are many types of mobile applications, each with its own advantages. For example, native apps perform better, while web apps don’t need to be customized for the platform or operating system (OS). Likewise, hybrid apps provide users with comfortable user experience. However, you may be wondering how long it takes to develop an app.

To give you an idea of how long the app development process takes, here’s a short guide.

App Idea & Research

app-idea-research

_Average time spent: two to five weeks _

This is the initial stage and a crucial step in setting the project in the right direction. In this stage, you brainstorm ideas and select the best one. Apart from that, you’ll need to do some research to see if your idea is viable. Remember that coming up with an idea is easy; the hard part is to make it a reality.

All your ideas may seem viable, but you still have to run some tests to keep it as real as possible. For that reason, when Web Developers are building a web app, they analyze the available ideas to see which one is the best match for the targeted audience.

Targeting the right audience is crucial when you are developing an app. It saves time when shaping the app in the right direction as you have a clear set of objectives. Likewise, analyzing how the app affects the market is essential. During the research process, App Developers must gather information about potential competitors and threats. This helps the app owners develop strategies to tackle difficulties that come up after the launch.

The research process can take several weeks, but it determines how successful your app can be. For that reason, you must take your time to know all the weaknesses and strengths of the competitors, possible app strategies, and targeted audience.

The outcomes of this stage are app prototypes and the minimum feasible product.

Java Vs. JavaScript: Know the Difference

What a mess it could be to share the same name — especially if you are a programming language. Even if you are already over 20 years old, IT newbies periodically confuse you with your namesake. This happens all the time with Java and JavaScript, although they are not related at all! As someone on the internet said. They correlate in much the same way as a car and a carpet.

Why do these two languages have such similar names? How do they differ from each other, and what else do they have in common? This article will provide the answers to these questions.

In the Beginning, It Was Java
