If one of the operands gets converted to NaN.If ( ~array.If one of the operands gets converted to a BigInt, while the other gets converted to a string that cannot be converted to a BigInt value (it throws a syntax error when passed to BigInt()). There are two cases where all four operators return false: Other operators, including >, >=, and <=, use the same algorithm as <. BigInt and number values can be compared together. Otherwise the values are compared as numeric values.If either value is NaN, the operator returns false.Strings are converted based on the values they contain, and are converted as NaN if they do not contain numeric values.Boolean values true and false are converted to 1 and 0 respectively.Otherwise JavaScript attempts to convert non-numeric types to numeric values:.If both values are strings, they are compared as strings, based on the values of the Unicode code points they contain.Note that although is called with the "number" hint (meaning there's a slight preference for the object to become a number), the return value is not converted to a number, since strings are still specially handled. How to representation not equal in JS Here is symbol representation of not equal. You have to use not equal in if/else statement. The left operand is always coerced before the right one. JavaScript if not means simply if the value of two operands are not equal it returns true. First, objects are converted to primitives by calling its (with "number" as hint), valueOf(), and toString() methods, in that order.The operands are compared with multiple rounds of coercion, which can be summarized as follows: Warning: unreachable code after return statement.Equal-to operator does not check if the type of values being compared is same. Since equal-to operator returns a boolean value, the above expression can be used as a condition in If-statement. Each operand can be a value or a variable. Warning: -file- is being assigned a //# sourceMappingURL, but already has one The syntax to use Equal-to Operator with operands is.TypeError: X.prototype.y called on incompatible type.TypeError: setting getter-only property "x".TypeError: Reduce of empty array with no initial value.TypeError: property "x" is non-configurable and can't be deleted.TypeError: invalid assignment to const "x".TypeError: invalid 'instanceof' operand 'x'.TypeError: cannot use 'in' operator to search for 'x' in 'y'.TypeError: can't redefine non-configurable property "x".TypeError: can't delete non-configurable array element.TypeError: can't define property "x": "obj" is not extensible.TypeError: can't convert BigInt to number.TypeError: can't assign to property "x" on "y": not an object.TypeError: "x" is not a non-null object.Synta圎rror: Using to indicate sourceURL pragmas is deprecated.Synta圎rror: unterminated string literal.Synta圎rror: unparenthesized unary expression can't appear on the left-hand side of '**'.Synta圎rror: unlabeled break must be inside loop or switch.Synta圎rror: Unexpected '#' used outside of class body.Synta圎rror: test for equality (=) mistyped as assignment (=)?.Synta圎rror: redeclaration of formal parameter "x".Synta圎rror: missing = in const declaration.Unicode character class escape: \p after property list.Character class escape: \d, \D, \w, \W, \s, \S.Enumerability and ownership of properties.
