  1. What are operators?
    Operators perform actions upon values

  2. What binary operators do you know?
    +, -, *, /, %, <, <=, >, >=

  3. What logical operators do you know?
    &&, ||, !


#122
  1. Operator is a symbol that manipulates the value
  2. <, >, <=, >=, ==, !=
  3. &&, ||, !

#123
  1. What are operators ?
    Ans. Operators are characters that represent an action, for example x is an arithmetic operator that represents multiplication. Putting an operator between two values will apply it to those values and produce a new value.

  2. What binary operators do you know ?
    Ans. Operators that use two operands are called binary operators. For example, Equal (==), Not equal (!=), Less than (<), Greater than (>), Greater than or equal to (>=), Less than or equal to (<=), Logical, AND (&&), Logical OR (||), Plus (+), Minus (-), Multiplication (*), Divide (/)

    Note : The minus operator can be used both as a binary operator and as a unary operator, for example [-(8-9)]

  3. What binary operators do you know ?
    Ans. Logical Operators allow a program to make a decision based on multiple conditions. The Logical operators are: op1 && op2 (Performs a logical AND of the two operands), op1 || op2 (Performs a logical OR of the two operands), !op1 (Performs a logical NOT of the operand).


#124

Operators are symbols that invoke actions or comparisons.

Some binary operators are >, >=, <, <=, ==, !=

Logical operators are && and || (“and” and “or” respectively).


#125
  1. What are operators?
  2. Simply put, operators do actions on values.

  3. What binary operators do you know?
  4. All a binary operator is, is an operator that operates on 2 values (or operands) to get a result:

  • + for addition
  • - for subtraction
  • * for multiplication
  • / for division
  • = for assigning
  • == for comparisons
  • % for modulus
  • > for greater than
  • < for less than
  • && for a logical AND
  • || for a logical OR
  • & for bitwise AND

Notice that pretty much all operators, including bitwise, logical, and comparison operators are considered binary operators because they do an operation on 2 operands.
  • What logical operators do you know?
  • &&, ||, and !
    AND, OR, and NOT are the only 3 logical operators I know.


    #126
    1. operators when applied to a value produces a new value
          • / %
    2. < <= >= == != && || !


    #127
    1. operatros are actions that are done on values
    2. +, -, *, /, %
    3. &&, ||, !

    #128
    1. Operators are an object used to manipulate values or strings
        • / * % < >

    #129
    What are operators?
    

    operators are used to assign values, compare values, perform arithmetic operations, and more.

    What binary operators do you know?
    
    • //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

    What logical operators do you know?
    

    && - Logical AND (usage, expression 1 && expression 2) - Description Returns expr1 if it can be converted to false; otherwise, returns expr2. Thus, when used with Boolean values, && returns true if both operands are true; otherwise, returns false.

    || - Logical OR (Usage expression 1 || expression2) - Description Returns expr1 if it can be converted to true; otherwise, returns expr2. Thus, when used with Boolean values, || returns true if either operand is true.

    ! - Logical NOT (Usage !expr) - Description Returns false if its single operand can be converted to true; otherwise, returns true.


    #130
    1. What are operators?
      Not all operators are symbols. Some are written as words. One example is the typeof operator, which produces a string value naming the type of the value you give it.
      console.log(typeof 4.5) // → number console.log(typeof “x”) // → string

    2. What binary operators do you know?
      JavaScript has a Boolean type, which has just two values, true and false.

    3. What logical operators do you know?
      JavaScript supports three logical operators: and, or, and not. These can be used to “reason” about Booleans.


    #131
    1. Operators are symbols or text used to alter the values( number, string, boolean and undefined).
      There are different types of operators such as arithmetic(+,-, /, *), binary ( true, false), concatenating(+), comparison (<, >, <=, >=, ==, ===, !=, !==)., Logic (&&, ||), unary operators (-, !, typeof) and ternary operators.
    2. Binary operators: Boolean type, True or False
      3.Logical operators: and(&&), or(||), not(!), (?).

    #132
    1. What are operators? special characters like + and -, punctuation and more can be used in different combinations to perform operations. Arithmetic Operators, Assignment Operators, Comparison Operators, Boolean Logical Operators, Increment and Decrement Operators.
    2. What binary operators do you know? +, -, *, /, >, <, >=, <=, %
      Operators that use two values are binary operators.
      Those that take one are called unary operators.
    3. What logical operators do you know? || (OR), && (AND), ! (NOT)

    #133

    1.Operators are words or symbols used to modify one or more values and produce a new one

    1. -, +, /, *
    • //Add
    • //Subtract
      / //Divided by
    • //Multiple
      % //Modulus
      < //Less than

    //Greater than
    <= // Less than or equal to

    == // Equal to

    Boolean expressions - Reading assignment

    What are operators?
    In Boolean logic, a statement can have two values, true or false.
    JavaScript operators are used to assign values, compare values, perform arithmetic operations, and more.
    • Assignment operators
    • Comparison operators
    • Arithmetic operators
    • Bitwise operators
    • Logical operators
    • String operators
    • Conditional (ternary) operator
    • Comma operator
    • Unary operators
    • Relational operators

    What binary operators do you know?

    JavaScript booleans can have one of two values: true or false.

    Binary Logical Operators (&&, ||)

    What logical operators do you know?

    Boolean Operators are simple words (AND, OR, NOT or AND NOT) used as conjunctions to combine or exclude keywords in a search, resulting in more focused and productive results.

    AND—requires both terms to be in each item returned. If one term is contained in the document and the other is not, the item is not included in the resulting list. (Narrows the search)
    Example: A search on stock market AND trading includes results contains: stock market trading; trading on the stock market; and trading on the late afternoon stock market
    OR—either term (or both) will be in the returned document. (Broadens the search)
    Example: A search on ecology OR pollution includes results contains: documents containing the world ecology (but not pollution) and other documents containing the word pollution (but not ecology) as well as documents with ecology and pollution in either order or number of uses.
    NOT or AND NOT ( dependent upon the coding of the database’s search engine)—the first term is searched, then any records containing the term after the operators are subtracted from the results. (Be careful with use as the attempt to narrow the search may be too exclusive and eliminate good records). If you need to search the word not, that can usually be done by placing double quotes (<< >>) around it.
    Example: A search on Mexico AND NOT city includes results contains: New Mexico; the nation of Mexico; US-Mexico trade; but does not return Mexico City or This city’s trade relationships with Mexico.


    #137
    1. Operators are active part of expressions which interact with variables and they give us return value or they assign values to the variables.
    2. Some of binary operators are: >,<, <=, =>, true, false,…
    3. Some of logical operators are: && (and), || (or), !(not),…
