What are operators?
Operators are atomic elements of Javascript programs that act on simple value types which are also atomic JavaScript elements. Not all operators are symbols, some are written in words. -
What binary operators do you know?
The minus operator can be used both as a binary operator and as a unary operator.
- What logical operators do you know?
The && operator represents logical and
The || operator denotes logical or It produces true if either of the values given to it is true.
That’s fine, but when do I get to build my crypto!
- What are operators?
You can combine and transform values with operators.

3. What logical operators do you know?

What are operators?
Operators are actions taken, to combine and transform values given. -

+, -, *, /, %, are some examples used as binary operators for arithmetic use . -

- What are operators?
An operator is a symbol that is used to perform an operation. They can be used for arithmetic, string concatenation, comparison or logic and can be unary, binary or even ternary. - What binary operators do you know?
Equal (==)

What is an operator?
An operator is a symbol or word which directs the computer to perform some type of action upon one or more values when placed next to said value(s).
Unary operators
- Values of the type “unary operator” are operators written as words, which take only one value as an input, and produce an output based on the single value input.
- Note: This is unlike “binary” operators which require a two input values in order to produce an output, or “ternary” operators which require three input values to produce an output.
- Examples of unary operators
- The typeof operator outputs a string value naming the type of the value that was inputed
- The – operator allows you to flip the sign of a numeric value inputed (e.g. from positive to negative or negative to positive).
- The ! operator allows you to flip a boolean value inputed
Binary operators
Arithmetic operators:
- Allow for doing arithmetic with numbers.
- Represented by “symbols” such as +, -, *, and /
- A less commonly used arithmetic symbol is the % symbol (known as the module or mod operator), which gives the remainder of a division expression.
- Arithmetic expressions with multiple symbols are computed in the following order of operations:
- Arithmetic within parentheses
- Multiplication, division, and remainders (if multiple of these appear next to each other, precedence is from left to right – this is known as left associativity)
- Addition and subtraction (if multiple of these appear next to each other, precedence is from left to right – this is known as left associativity)
Comparison operators:
- Greater than, expressed using the symbolic binary operator >
- Less than, expressed using the symbolic binary operator <
- Exactly equal to, expressed using the symbolic binary operator ==
- Less than or equal to, expressed using the symbolic binary operator <=
- Greater than or equal to, expressed using the symbolic binary operator >=
Logical operators:
- “And”, expressed using the symbolic binary operator &&
- “Or”, expressed using the symbolic binary operator ||
- Note: “Not”, expressed using the symbol !, is also a logical operator, but it is a unary operator not a binary operator.
Ternary operators (i.e. conditional operator)
- The conditional operator, the only ternary operator in the JS language, is structured as follows
- Boolean value ? value if true : value if false

- Operators are the action for the values.
- Binary operations in JavaScript are true and false. These are represented by:
-
- greater than
- < - less than
-
= - greater than or equal to
- < = - less than or equal to
- Logical operations are:
- && - and

Logical operator are operators that specifically perform comparison based on a set of rules without which renders invalid.
Logical Operators evaluates values to either true or false, yes or no, right or wrong based on preset/pre-determine set of conditions.

In JavaScript operators are used to assign values, perform arithmetric operations, compare values, assign conditions, logic, typeof or deletion ect. if an operator takes one value then it is a unary operator, while if the operator uses two values, its is termed a binary operator.
-
A bitwise OR is a binary operation that takes two bit patterns of equal length and performs the logical inclusive OR operation on each pair of corresponding bits. The result in each position is 0 if both bits are 0, while otherwise the result is 1. For example: 0101 (decimal 5) OR 0011 (decimal 3) = 0111 (decimal 7).

The concept of logical operators is simple. They allow a program to make a decision based on multiple conditions. Each operand is considered a condition that can be evaluated to a true or false value. Then the value of the conditions is used to determine the overall value of the op1 operator op2 or !
