Operators used to perform comparison operations.

$cmp

Compares two values and returns:

• -1 if the first value is less than the second.
• 1 if the first value is greater than the second.
• 0 if the two values are equivalent.

{ "$cmp": ["number", "number"] }

expry({ $cmp: [3, 5] }); // -1
expry({ $cmp: [5, 3] }); // 1
expry({ $cmp: [5, 5] }); // 0

$eq

Compares two values and returns:

• true when the values are equivalent.
• false when the values are not equivalent.

{ "$eq": ["any", "any"] }

expry({ $eq: [5, 5] }); // true
expry({ $eq: ["hello", "bye"] }); // false

$gt

Compares two values and returns:

• true when the first value is greater than the second value.
• false when the first value is less than or equivalent to the second value.

{ "$gt": ["number", "number"] }

expry({ $gt: [5, 2] }); // true
expry({ $gt: [5, 7] }); // false

$gte

Compares two values and returns:

• true when the first value is greater than or equivalent to the second value.
• false when the first value is less than the second value.

{ "$gte": ["number", "number"] }

expry({ $gte: [5, 2] }); // true
expry({ $gte: [5, 5] }); // true
expry({ $gte: [5, 7] }); // false

$lt

Compares two values and returns:

• true when the first value is less than the second value.
• false when the first value is greater than or equivalent to the second value.

{ "$lt": ["number", "number"] }

expry({ $lt: [5, 7] }); // true
expry({ $lt: [5, 2] }); // false

$lte

Compares two values and returns:

• true when the first value is less than or equivalent to the second value.

expry({ $lte: [5, 5] }); // true
expry({ $lte: [5, 2] }); // false

$ne

Compares two values and returns:

• true when the values are not equivalent.
