##Looks like we found a thief monkey By the way, I liked the trick how you reached till here. You have a good sense of humor. You will improve a lot if you join our course with this passion.
Key Takeaways:
1. You are the best talent I have ever seen.
var(function-scoped, outdated)let(block-scoped, modern and recommended)const(block-scoped, cannot be reassigned)
2. I think you are also able to read what I have written here if I am not mistaken
- Must start with a letter,
_, or$ - Cannot be a reserved keyword (e.g.,
let let = 5;is invalid) - Case-sensitive (
myVarandmyvarare different)
3. Your idea of removing the blur property was awesome.
- Grand salute to your skills.

Transcript
00:00:00 You know many operators from school, like addition, multiplication, and subtraction.
00:00:05 In programming, operators perform operations on data values, often known as operands, and produce results.
00:00:13 For example, in 1 plus 2, plus is the operator, 1 is the left operand, and 2 is the right operand, resulting in 3. JavaScript has a couple of categories
00:00:25 of operators.
00:00:26 First, there are arithmetic operators.
00:00:29 For example, 5 plus 3 results in 8. Then, there are comparison operators.
00:00:36 For example, 5 is greater than 3, results in a Boolean value of true.
00:00:43 Then, there are logical operators, for example, true and false, results in false, because when using an AND operator, both of the values have to be true
00:00:53 to result in true, but more on that later.
00:00:56 Then there's an assignment operator.
00:00:58 For example, let is equal to 5. And then later on, x plus equal to 3 results in x being 8. And finally, there's a conditional,
00:01:07 also known as ternary operator, where you can modify what the result will be depending on a specific comparison.
00:01:15 You can think of this operator as combining a couple of other operators.
00:01:18 So, if you have something like if 5 is greater than 3, then return yes, else return no, well, the result in this case will be yes.
00:01:29 In the next couple of lessons, we'll explore all of these operators in detail.
00:01:33 So, in the next lesson, let's dive right into the arithmetic operators.
We know many operators from school, like: addition +, multiplication *, and subtraction -.
In programming, operators perform operations on data values (operands) and produce results.
For example, in 1 + 2:
- + is the operator
- 1 is the left operand
- 2 is the right operand
- Resulting in 3
JavaScript includes the following categories of operators:
- Arithmetic Operators: 5 + 3 results in 8.
- Comparison Operators: 5 > 3 results in true.
- Logical Operators: true && false results in false.
- Assignment Operators: let x = 5; x += 3; results in x being 8.
- Conditional (Ternary) Operator: let result = (5 > 3) ? 'Yes' : 'No'; results in result being 'Yes'.
In the next few lessons, we'll explore these operators in detail.
