How to start writing less error-prone code in JavaScript

Everything in JavaScript is an object!’. We said that this assertion is false. Many things in JavaScript can behave like an object, but that doesn’t mean it’s the object. We can say we have three types of objects (objects, functions and arrays) in JavaScript.

In ECMAScript Specification, the functions aren’t on the type list. Intuitively, function values have a specific behaviour, that is different from values that are numbers - so isn’t it a type? JavaScript refers to functions as a sub-type of the object type - sometimes refers to them as a callable object.

Conclusion: Functions are sort of type, but a sub-type - not a top level type…

Embold Is Like Autocorrect For Code, Says Vishal Rai, Founder & CEO

In our digital world, software is king. In a world so heavily dependent on software, poor code quality can result in grave consequence, from billions of dollars in lost revenue, to even fatal accidents. Here’s where Embold comes in—a static code analysis product aimed at empowering developers to do their best work.

Embold is a general-purpose static code analyser that has been designed for developers to analyse and improve their code by identifying issues across four dimensions, including design and duplication. We, at Analytics India Magazine, spoke to founder and CEO, Vishal Rai, to understand how Embold can detect anti-patterns in code for seamless integration.

Embold started a decade ago, with the vision of creating a product that can revolutionise the way developers write and design code. According to Vishal Rai, the idea was to develop a tool for software engineers and developers to write code faster and of better quality. And, after a time of extensive research and development, Vishal Rai, along with his partner Sudarshan Bhide launched their product in 2018.


Play

“We have noticed an interesting trend — as teams started becoming bigger, the issues in software started increasing as well and it was very frustrating when you were on programs which weren’t achieving their stated goals because of poor quality,” said Rai. “And that’s where we saw the opportunity of helping companies to write the product as great as Google or Apple and decided to reinvent software analytics.”

Embold — Empowering Developers to Reach Their Highest Potential

Developers always undergo immense pressure of building their products faster at the best quality possible, and such pressure can lead to compromised code quality. This impact of one line of code or one weak link can create significant issues and can massively affect the entire company. And that is why Rai believes that developers need support in being more productive. With Embold, Vishal and Sudharshan brought in a technology that can help developers be more efficient in their work and make the process of software development easy. Explaining the technology, Rai compared it with “autocorrect for code.” He said, “If you look at the legacy tools, they were built for the waterfall model, aka linear-sequential life cycle model, where one release took six months which gave enough time to test the tools. But in the current time, everything is fast, and thus developers require tools that can help them work fast and give them feedback that can be easily implemented in their workflow.” And that’s where Embold’s platform fits into the workflow that helps them find problems and maintain their code.  As a matter of fact, Rai acknowledges that there have been many great tools, already in the market, but all of them have been created for great engineers. However, today, not every engineer is necessarily as experienced as others, and in such cases, it is imperative to make tools that are easy to use and help developers analyse their software. “Embold has been built for the future, the technologies that we have ingrained have neural networks, state-of-the-art in-memory databases and analysers that are far more evolved than legacy tools,” said Rai. “Embold has been created to enable people who aren’t as skilled to write better codes. Not only it fills the skills gap but also brings the new age developers closer to the best developers on the planet.”

What is JavaScript - Stackfindover - Blog

Who invented JavaScript, how it works, as we have given information about Programming language in our previous article ( What is PHP ), but today we will talk about what is JavaScript, why JavaScript is used The Answers to all such questions and much other information about JavaScript, you are going to get here today. Hope this information will work for you.

Who invented JavaScript?

JavaScript language was invented by Brendan Eich in 1995. JavaScript is inspired by Java Programming Language. The first name of JavaScript was Mocha which was named by Marc Andreessen, Marc Andreessen is the founder of Netscape and in the same year Mocha was renamed LiveScript, and later in December 1995, it was renamed JavaScript which is still in trend.

What is JavaScript?

JavaScript is a client-side scripting language used with HTML (Hypertext Markup Language). JavaScript is an Interpreted / Oriented language called JS in programming language JavaScript code can be run on any normal web browser. To run the code of JavaScript, we have to enable JavaScript of Web Browser. But some web browsers already have JavaScript enabled.

Today almost all websites are using it as web technology, mind is that there is maximum scope in JavaScript in the coming time, so if you want to become a programmer, then you can be very beneficial to learn JavaScript.

JavaScript Hello World Program

In JavaScript, ‘document.write‘ is used to represent a string on a browser.

<script type="text/javascript">
	document.write("Hello World!");
</script>

How to comment JavaScript code?

  • For single line comment in JavaScript we have to use // (double slashes)
  • For multiple line comments we have to use / * – – * /
<script type="text/javascript">

//single line comment

/* document.write("Hello"); */

</script>

Static Code Analysis: What It Is? How to Use It?

Static code analysis refers to the technique of approximating the runtime behavior of a program. In other words, it is the process of predicting the output of a program without actually executing it.

Lately, however, the term “Static Code Analysis” is more commonly used to refer to one of the applications of this technique rather than the technique itself — program comprehension — understanding the program and detecting issues in it (anything from syntax errors to type mismatches, performance hogs likely bugs, security loopholes, etc.). This is the usage we’d be referring to throughout this post.

“The refinement of techniques for the prompt discovery of error serves as well as any other as a hallmark of what we mean by science.”

  • J. Robert Oppenheimer

Outline

We cover a lot of ground in this post. The aim is to build an understanding of static code analysis and to equip you with the basic theory, and the right tools so that you can write analyzers on your own.

We start our journey with laying down the essential parts of the pipeline which a compiler follows to understand what a piece of code does. We learn where to tap points in this pipeline to plug in our analyzers and extract meaningful information. In the latter half, we get our feet wet, and write four such static analyzers, completely from scratch, in Python.

Note that although the ideas here are discussed in light of Python, static code analyzers across all programming languages are carved out along similar lines. We chose Python because of the availability of an easy to use ast module, and wide adoption of the language itself.

How does it all work?

Before a computer can finally “understand” and execute a piece of code, it goes through a series of complicated transformations:

static analysis workflow

As you can see in the diagram (go ahead, zoom it!), the static analyzers feed on the output of these stages. To be able to better understand the static analysis techniques, let’s look at each of these steps in some more detail:

Scanning

The first thing that a compiler does when trying to understand a piece of code is to break it down into smaller chunks, also known as tokens. Tokens are akin to what words are in a language.

A token might consist of either a single character, like (, or literals (like integers, strings, e.g., 7Bob, etc.), or reserved keywords of that language (e.g, def in Python). Characters which do not contribute towards the semantics of a program, like trailing whitespace, comments, etc. are often discarded by the scanner.

Python provides the tokenize module in its standard library to let you play around with tokens:

Python

1

import io

2

import tokenize

3

4

code = b"color = input('Enter your favourite color: ')"

5

6

for token in tokenize.tokenize(io.BytesIO(code).readline):

7

    print(token)

Python

1

TokenInfo(type=62 (ENCODING),  string='utf-8')

2

TokenInfo(type=1  (NAME),      string='color')

3

TokenInfo(type=54 (OP),        string='=')

4

TokenInfo(type=1  (NAME),      string='input')

5

TokenInfo(type=54 (OP),        string='(')

6

TokenInfo(type=3  (STRING),    string="'Enter your favourite color: '")

7

TokenInfo(type=54 (OP),        string=')')

8

TokenInfo(type=4  (NEWLINE),   string='')

9

TokenInfo(type=0  (ENDMARKER), string='')

(Note that for the sake of readability, I’ve omitted a few columns from the result above — metadata like starting index, ending index, a copy of the line on which a token occurs, etc.)
