All about the beautiful language we all love and care for! This category is for JavaScript and different nuances in the JavaScript programming language.
This is a somewhat common interview question that asks the following. Consider there is an array holding sorted numbers in an established range. For our example, we’ll propose numbers ranging from 1 to 100. No duplicate elements are allowed. Also, there is only one element missing. What is that element? Or to rephase it – how to find the missing number in a given integer array?

Prototypes are simply mechanisms by which Javascript objects inherit properties from other JavaScript objects. We already know how to create objects using object notation, and how to add or remove properties from such objects. But what if we would need to create hundreds of different… Read More »Understanding Javascript prototypes
For a refresher on the general concept of promises by yours truly click here. As you already know, promises solve a common problem when writing asynchronous code using callbacks – how to handle nested and burdensome sequences of callback functions. Instead of using callback methods,… Read More »Difference between Promise.all() and Promise.race()
Generators are yet another addition to the JS standard introduced in the ES6 edition of the language. Generators are a new addition to JavaScript, although they have been existing in other programming languages such as Python, PHP, and C#. What is a generator? Generators are… Read More »JavaScript generators
Apart from parameters being explicitly defined inside the function definition, there are two additional silent parameters getting passed down to the function itself. These silent parameters are called implicit parameters: this and arguments. They are not listed in the signature of any function but can… Read More »Using this and arguments
