[−][src]Enum boa::syntax::ast::op::CompOp
A comparison operator compares its operands and returns a logical value based on whether the comparison is true.
The operands can be numerical, string, logical, or object values. Strings are compared based on standard
lexicographical ordering, using Unicode values. In most cases, if the two operands are not of the same type,
JavaScript attempts to convert them to an appropriate type for the comparison. This behavior generally results in
comparing the operands numerically. The sole exceptions to type conversion within comparisons involve the ===
and !==
operators, which perform strict equality and inequality comparisons. These operators do not attempt to convert the operands
to compatible types before checking equality.

Variants
The equality operator converts the operands if they are not of the same type, then applies strict comparison.
Syntax: y == y
If both operands are objects, then JavaScript compares internal references which are equal when operands refer to the same object in memory.
More information:
The inequality operator returns true if the operands are not equal.
Syntax: x != y
If the two operands are not of the same type, JavaScript attempts to convert the operands to an appropriate type for the comparison. If both operands are objects, then JavaScript compares internal references which are not equal when operands refer to different objects in memory.
More information:
The identity operator returns true if the operands are strictly equal with no type conversion.
Syntax: x === y
Returns true
if the operands are equal and of the same type.
More information:
The non-identity operator returns true if the operands are not equal and/or not of the same type.
Syntax: x !== y
Returns true
if the operands are of the same type but not equal, or are of different type.
More information:
The greater than operator returns true if the left operand is greater than the right operand.
Syntax: x > y
Returns true
if the left operand is greater than the right operand.
More information:
The greater than or equal operator returns true if the left operand is greater than or equal to the right operand.
Syntax: x >= y
Returns true
if the left operand is greater than the right operand.
More information:
The less than operator returns true if the left operand is less than the right operand.
Syntax: x < y
Returns true
if the left operand is less than the right operand.
More information:
The less than or equal operator returns true if the left operand is less than or equal to the right operand.
Syntax: x <= y
Returns true
if the left operand is less than or equal to the right operand.
More information:
The in
operator returns true if the specified property is in the specified object or its prototype chain.
Syntax: prop in object
Returns true
the specified property is in the specified object or its prototype chain.
