海外TECH	DEV Community	Compare Things In JavaScript [Explained in A Grows Amount of Detail]	https://dev.to/cleancodestudio/how-to-actually-compare-things-in-javascript-testing-comparison-operations-259j	Compare Things In JavaScript Explained in A Grows Amount of Detail Ever get stuck wondering if you need a bora borisLooselyEqual a b orisStrictlyEqual a b I know I sure have Testing and Comparison Operations the actual definitions This is content pulled directly from ECMAscript specifications Not written by me It defines specifically how comparisons testing operations work to an almost grows amount of detail Good reference to have if you re unsure whether you need two equal signs or one equal sign to check if two things are the same or different IsArray argument The abstract operation IsArray takes argument argument It performs the following steps when called If Type argument is not Object return false If argument is an Array exotic object return true If argument is a Proxy exotic object then a If argument ProxyHandler is null throw a TypeError exception b Let target be argument ProxyTarget c Return  IsArray target Return false IsCallable argument The abstract operation IsCallable takes argument argument an ECMAScript language value It determines if argument is a callable function with a Call internal method It performs the following steps when called If Type argument is not Object return false If argument has a Call internal method return true Return false IsConstructor argument The abstract operation IsConstructor takes argument argument an ECMAScript language value It determines if argument is a function object with a Construct internal method It performs the following steps when called If Type argument is not Object return false If argument has a Construct internal method return true Return false IsExtensible O The abstract operation IsExtensible takes argument O an Object It returns a completion record which if its Type is normal has a Value which is a Boolean It is used to determine whether additional properties can be added to O It performs the following steps when called Assert Type O is Object Return O IsExtensible IsIntegralNumber argument The abstract operation IsIntegralNumber takes argument argument It determines if argument is a finite integral Number value It performs the following steps when called If Type argument is not Number return false If argument is NaN ∞𝔽 or ∞𝔽 return false If floor abs ℝ argument ≠abs ℝ argument return false Return true IsPropertyKey argument The abstract operation IsPropertyKey takes argument argument an ECMAScript language value It determines if argument is a value that may be used as a property key It performs the following steps when called If Type argument is String return true If Type argument is Symbol return true Return false IsRegExp argument The abstract operation IsRegExp takes argument argument It performs the following steps when called If Type argument is not Object return false Let matcher be  Get argument match If matcher is not undefined return  ToBoolean matcher If argument has a RegExpMatcher internal slot return true Return false IsStringPrefix p q The abstract operation IsStringPrefix takes arguments p a String and q a String It determines if p is a prefix of q It performs the following steps when called Assert Type p is String Assert Type q is String If q can be the string concatenation of p and some other String r return true Otherwise return false NoteAny String is a prefix of itself because r may be the empty String SameValue x y The abstract operation SameValue takes arguments x an ECMAScript language value and y an ECMAScript language value It returns a completion record whose Type is normal and whose Value is a Boolean It performs the following steps when called If Type x is different from Type y return false If Type x is Number or BigInt then a Return  Type x sameValue x y Return  SameValueNonNumeric x y NoteThis algorithm differs from the IsStrictlyEqual sec isstrictlyequal Algorithm in its treatment of signed zeroes and NaNs SameValueZero x y The abstract operation SameValueZero takes arguments x an ECMAScript language value and y an ECMAScript language value It returns a completion record whose Type is normal and whose Value is a Boolean It performs the following steps when called If Type x is different from Type y return false If Type x is Number or BigInt then a Return  Type x sameValueZero x y Return  SameValueNonNumeric x y NoteSameValueZero differs from SameValue sec samevalue only in its treatment of 𝔽and 𝔽 SameValueNonNumeric x y The abstract operation SameValueNonNumeric takes arguments x an ECMAScript language value and y an ECMAScript language value It returns a completion record whose Type is normal and whose Value is a Boolean It performs the following steps when called Assert Type x is not Number or BigInt Assert Type x is the same as Type y If Type x is Undefined return true If Type x is Null return true If Type x is String then a If x and y are exactly the same sequence of code units same length and same code units at corresponding indices return true otherwise return false If Type x is Boolean then a If x and y are both true or both false return true otherwise return false If Type x is Symbol then a If x and y are both the same Symbol value return true otherwise return false If x and y are the same Object value return true Otherwise return false IsLessThan x y LeftFirst The abstract operation IsLessThan takes arguments x an ECMAScript language value y an ECMAScript language value and LeftFirst a Boolean It provides the semantics for the comparison x lt y returning true false or undefined which indicates that at least one operand is NaN The LeftFirst flag is used to control the order in which operations with potentially visible side effects are performed upon x and y It is necessary because ECMAScript specifies left to right evaluation of expressions If LeftFirst is true the x parameter corresponds to an expression that occurs to the left of the y parameter s corresponding expression If LeftFirst is false the reverse is the case and operations must be performed upon y before x It performs the following steps when called If the LeftFirst flag is true then a Let px be  ToPrimitive x number b Let py be  ToPrimitive y number Else a NOTE The order of evaluation needs to be reversed to preserve left to right evaluation b Let py be  ToPrimitive y number c Let px be  ToPrimitive x number If Type px is String and Type py is String then a If IsStringPrefix py px is true return false b If IsStringPrefix px py is true return true c Let k be the smallest non negative integer such that the code unit at index k within px is different from the code unit at index k within py There must be such a k for neither String is a prefix of the other d Let m be the integer that is the numeric value of the code unit at index k within px e Let n be the integer that is the numeric value of the code unit at index k within py f If m lt n return true Otherwise return false Else a If Type px is BigInt and Type py is String then i Let ny be  StringToBigInt py ii If ny is NaN return undefined iii Return BigInt lessThan px ny b If Type px is String and Type py is BigInt then i Let nx be  StringToBigInt px ii If nx is NaN return undefined iii Return BigInt lessThan nx py c NOTE Because px and py are primitive values evaluation order is not important d Let nx be  ToNumeric px e Let ny be  ToNumeric py f If Type nx is the same as Type ny return Type nx lessThan nx ny g Assert Type nx is BigInt and Type ny is Number or Type nx is Number and Type ny is BigInt h If nx or ny is NaN return undefined i If nx is ∞𝔽or ny is ∞𝔽 return true j If nx is ∞𝔽or ny is ∞𝔽 return false k If ℝ nx lt ℝ ny return true otherwise return false Note Step step arc string check differs from step c step binary op string check in the algorithm that handles the addition operator sec applystringornumericbinaryoperator by using the logical and operation instead of the logical or operation Note The comparison of Strings uses a simple lexicographic ordering on sequences of code unit values There is no attempt to use the more complex semantically oriented definitions of character or string equality and collating order defined in the Unicode specification Therefore String values that are canonically equal according to the Unicode standard could test as unequal In effect this algorithm assumes that both Strings are already in normalized form Also note that for strings containing supplementary characters lexicographic ordering on sequences of UTF code unit values differs from that on sequences of code point values IsLooselyEqual x y The abstract operation IsLooselyEqual takes arguments x an ECMAScript language value and y an ECMAScript language value It provides the semantics for the comparison x y returning true or false It performs the following steps when called If Type x is the same as Type y then a Return IsStrictlyEqual x y If x is null and y is undefined return true If x is undefined and y is null return true NOTE This step is replaced in section B If Type x is Number and Type y is String return IsLooselyEqual x  ToNumber y If Type x is String and Type y is Number return IsLooselyEqual ToNumber x y If Type x is BigInt and Type y is String then a Let n be  StringToBigInt y b If n is NaN return false c Return IsLooselyEqual x n If Type x is String and Type y is BigInt return IsLooselyEqual y x If Type x is Boolean return IsLooselyEqual ToNumber x y If Type y is Boolean return IsLooselyEqual x  ToNumber y If Type x is either String Number BigInt or Symbol and Type y is Object return IsLooselyEqual x  ToPrimitive y If Type x is Object and Type y is either String Number BigInt or Symbol return IsLooselyEqual ToPrimitive x y If Type x is BigInt and Type y is Number or if Type x is Number and Type y is BigInt then a If x or y are any of NaN ∞𝔽 or ∞𝔽 return false b If ℝ x ℝ y return true otherwise return false Return false IsStrictlyEqual x y The abstract operation IsStrictlyEqual takes arguments x an ECMAScript language value and y an ECMAScript language value It provides the semantics for the comparison x y returning true or false It performs the following steps when called If Type x is different from Type y return false If Type x is Number or BigInt then a Return  Type x equal x y Return  SameValueNonNumeric x y NoteThis algorithm differs from the SameValue Algorithm in its treatment of signed zeroes and NaNs	2021-08-08 04:37:16
