Hi,guys in this lesson we learnt the increment with the assignment operator

here is the summary
You can easily decrement or decrease a variable by one with the -- operator.

i--;

is the equivalent of

i = i - 1;

Note
The entire line becomes i--;, eliminating the need for the equal sign.

Change the code to use the -- operator on myVar.

Prepare for JavaScript interview questions focusing on closures, functions, and currying. Throughout the course, you'll delve into various aspects of JavaScript, such as function declarations, expressions, scopes, and hoisting, as well as learning about advanced concepts like closures and lexical scope. You'll also gain a deeper understanding of currying and its practical applications in JavaScript.

In this epidode we talk about adding, subtracting, multiplying, dividing and incrementing in JavaScript. I attempted to make this video a little more humoruos than the previous videos to make learning this stuff a little more entertaining. The lessons we go over in this video are very basic and I personally am looking forward to some more intence work.

Let me know if you need anything from me.

Cheers,
Theodore.

Join me in solving coding problems, in real time. I'm not just going to tell you the solution... you're going to watch me solve the problem. I see too many posts on sites like Reddit where people are worried about diving in and writing code, or they want to break out of tutorial hell. I know I used to be intimidated seeing instructors blasting through code in one try... but then I realized it's scripted.

I've been coding in JavaScript for 5 years: see if you can beat me to the solution, and then let's compare notes.

Open the same problem on freeCodeCamp.org: https://www.freecodecamp.org/l....earn/javascript-algo

Did you solve the problem before I could? What'd you do that I didn't do? How fast was your solution? Let me know in the comments below!
