Unveiling the Secrets of Variables: Python, Javascript, and Swift Compared

In this video, we're going to compare the three main programming languages: Javascript, Python, and Swift. We'll see what variables are in each language, and how they work. We'll also look at some common app development tasks in each language, and see how they're implemented in each language.

If you're looking to learn more about computer science, or to brush up on your skills in one of these languages, then this video is for you! By the end, you'll have a better understanding of what variables are in each language, and how they're used in computer programming.

How variables work in different languages , compare their working and absence of value in Python, Javascript and Swift . Use google colab, Xcode playgrounds and chrome developer tools.What are the ways in which the declaration and the initialisation of variables differ in these languages, understand the concepts in three different languages so you do not need to understand the same concept again and again.The absence of value is dealt with differently in all three languages, python, javascript and swift and for good reason, all three were made with a different purpose in mind, but they all do it very elegantly. Learn the syntax and the logic behind variables and how they operate.
