  1. a operator does something to a value, like multiply it
  2. Binary do something like multiply or compare two values, ex. a*b
  3. Logical operators compare two inputs, &&, ==, !=, ||

1 operaters are the part of a function that dictate what to do with the values

2 + - / *

3 if, > < =

#686

3. What logical operators do you know?

Hello sir, those are not logical operators, they are “Comparison Operators”, the logical operators used in Javascript are:

&& = AND
Example:
(x < 10 && y > 1) is true

|| OR
Example:
(x == 5 || == 5) is false

! = NOT
Example:
!(x == y) is true

Hope this gives you a clear view of the subject, keep learning! :slight_smile:

If you have any doubt, please let us know so we can help you!

Hello sir, i just see some dots on the answer to the second question, if you please redesign it would be awesome!

  1. What are operators?
  • Operators are specific functions used for values to interact with each other and create a new value
  1. What binary operators do you know?
  • ==, !=, ===, !==, <,>, >=, +, -, *, /, % or pretty much any operator which will compute two values and give an output
  1. What logical operators do you know?
  • “&&” and || not"|"

  1. What are operators?
    – Operators are used to compose,compare or calculate a new value out of one or more values.there is differente type of operators unary,binary or ternary

  2. What binary operators do you know?
    ‘=’ equal
    ‘+’ plus
    '- 'minus
    ‘*’ multiply
    ‘/’ dvide
    ‘%’ modulus
    ‘!=’ not equal
    ‘===’ absolutely equal
    '< ’ less than
    ‘>’ greater than
    ‘<=’ less than or equal
    ‘>=’ greater or equal

  3. What logical operators do you know?
    ‘&&’ and
    ‘||’ or
    ‘!’ not

  1. Operators are elements that can manipulate values.

(==) equal to
(!=) not equal
(<) less
(>) greater
(>=) greater or equal to
(<=) less or equal to
(&&) Logical AND
(II) Logical OR
(-) minus
(+) plus
(*) multiple
(/) divide

And (&&)
Or (II)
Not (!)

1- Operators take a value (or 2 if a binary operator) and creates a new value by applying the operator to it
2- arithmetic (+,-,*,%,/), comparison (==,<=,>=,===,!==,<,>) and logical (&&,||)
3- &&,||

  1. What are operators?
    An operator performs some operation on single or multiple operands (data value) and produces a result.

  2. What binary operators do you know?
    Operators that use two values are called binary operators. Some binary operators are +, x, /, minus

  3. What logical operators do you know?
    There are also some operations that can be applied to Boolean values. JavaScript supports three logical operators: and, or, and not. (&&, ||, !)

Hi @rbrownlow!

Good examples of binary and logical operators! :ok_hand:
… except that…

… is an example of a ternary operator, which can be used instead of if...else conditional execution:

if (true) {
   console.log(1);
} else {
   console.log(2);
}

However, these aren’t actually good examples, as the condition (true) will always evaluate to true , so both of them will always output 1.

Can you think of a better example of a ternary operator? :thinking:

  1. Operator is a symbol, which means a specific process of manipulating with operands and at the end processing some kind of result.
  2. Binary operators: <, >, ===, ==, =, *, ˆ, -,+, /, %.
  3. Logical Operators: OR ||, AND &&.

  1. An operator preforms an action on a variable, such as doing arithmetic or checking how large or small it is compared to another variable.

  2. Binary operators perform arithmetic on variables, such as add or subtract.

  • //Add
  • //Subtract
    / //Divided by
  • //Multiple
    % //Modulus
    < //Less than

//Greater than
& //AND
| //OR
^ //XOR
~ //Invert each bits
<< //Move all bits onto the left

//Move all bits onto the right

//Move all bits onto the right and fill left end with 0

  1. Logical operators determine the relationship between two variables, and returns a boolean answer. For example, 2 > 3 would return false.

, <. ==, ===, >=, <=, !==, !===
&&, ||, !

  1. Operators are basically like calculator function they take multiple values and change them based on the operator. ie: The + operator will add 2 values together.

  2. Binary operators that I know are: Plus, Minus, Multiplication, Division, Remainder.

  3. Logical operators that I know are: and, or, and not
