  JavaScript interview questions

This post will cover the JavaScript questions I have encountered and have seen during my programming career. They will mainly focus on vanilla JavaScript though there are lots of excellent frameworks out there and many people are using them in their daily work. this keyword this keyword is an very important but easy to confuse concept in JavaScript since it is always referring to the calling object of the function. 1. What will be the output of below code snippet? function User(name) { this....

  Multitasking vs multiprogramming

As all these processing are the part of computer functions. You should not be confused between these processes.In computing, multitasking is a method by which multiple tasks are performed by the user also known as processes, share common processing resources such as a CPU. CPU is actively executing more than one task at a time. Multitasking solves the problem by scheduling the tasks instructions. Which task may be the one running at any...

  Tips for Putting a Price on Your Work

WHEN I first started as a freelance writer, I was eager to sell myself — but not eager to have to discuss money. So I more or less took whatever was offered. Then I read somewhere that no matter what price a new client states, you always say in a polite but firm tone, “I expected more.” The first time I tried it, I was sweating and I doubt my tone was firm — it probably sounded more like pleading — but to my great surprise, it worked. With th...

  How small should a function be?

"The well-designed functions are often relatively small, large function design is often a mess or there is a lot of room for optimization."Maybe you think there is no need to discuss the size of functions, because the nature of the function design is cohesive, its size is only its manifestations. But it is necessary to discuss about the size of function because the statement above .First let's understand the concept of minimum code processing unit : a basic operation (assignment, comparison, etc...

  Why Javascript is a Joy

I’m probably a bit biased – being a front-end web developer for a few years will do that – but I really enjoy writing Javascript. I’ve recently retreated from pure coding the last few months, but I got an opportunity this past week to jump back into some tasks, and it has reminded me how fun it is to dive into our[1] front-end codebase. Yes, Javascript can be surprisingly elegant yet completely infuriating, and all on the same line of code; for a long time, ...

  The "C is Efficient" Language Fallacy

I came across an article yesterday about programming languages, which hit on one of my major peeves, so I can't resist responding. The article is at greythumb.org, and it's called Programmer's rant: what should and should not be added to C/C++. It's a variation on the extremely common belief that C and C++ are the best languages to use when you need code to run fast. They're not. They're good at things that need to get very close to the hardware - not in the efficiency sense, but in the...

  Pointers, arrays, and string literals

A recently posted question on Stack Overflow highlighted a common misconception about the role of pointers and arrays held by many programmers learning C.The confusion stems from a misunderstanding concerning the role of pointers and strings in C. A pointer is an address in memory. It often points to an index in an array, such as in the function strtoupper in the following code:void strtoupper(char *str) { if (str) { // null ptr check, courtesy of Michael while (...

  Why Do Some People Learn Faster?

The physicist Niels Bohr once defined an expert as “a person who has made all the mistakes that can be made in a very narrow field.” Bohr’s quip summarizes one of the essential lessons of learning, which is that people learn how to get it right by getting it wrong again and again. Education isn’t magic. Education is the wisdom wrung from failure. A new study, forthcoming in Psychological Science, and led by Jason Moser at Michigan State University, expands on this ...

  10 Tips To Make Your C Program Effective

The beauty of any code lies not only in finding the solution to a given problem but is in its simplicity, effectiveness, compactness and efficiency( memory ). Designing the code is harder than actually implementing it. Hence every programmer should keep a couple of basic things in mind while programming in C. Here we introduce you to such 10 ways of standardizing your C code. 1. Avoid unwarranted function calls Consider the following two functions: view source print? 1 void str_print( c...
