Logical Operators in MongoDB in Hindi ( $not, $and, $or & $nor)

In MongoDB, logical operators are used to combine multiple expressions in a query or to perform logical operations on individual expressions.

$and: This operator performs a logical AND operation on an array of expressions and returns true if all the expressions are true.

$or: This operator performs a logical OR operation on an array of expressions and returns true if at least one of the expressions is true.

$not: This operator performs a logical NOT operation on a single expression and returns true if the expression is false and false if the expression is true.

Employee.find({ $and: [{ age: { $lte: 11 } }, { hobbies: "Walk" }] });
Employee.find({ $and: [{ age: { $lte: 11 } }, { hobbies: { $eq: "Walk" } }] });
Employee.find({
$and: [{ age: { $lte: 11 } }, { hobbies: { $in: ["Walk"] } }],
