海外TECH	DEV Community	What are the three dots (...) or spread operator in Javascript?	https://dev.to/smpnjn/what-are-the-three-dots-or-spread-operator-in-javascript-54a7	What are the three dots or spread operator in Javascript The spread operator spread syntax or dots is a type of syntax in Javascript which is used by both function calls and in arrays objects It has a multitude of different uses so let s take a look at how we use the spread syntax in real Javascript code In function callsWe can use the dots in Javascript function calls to convert an array into a set of arguments for a function Let s look at an example Below our array is converted into the values for x y z and a let numbers let myFunction function x y z a return x y z a Returns myFunction numbers This can be combined with other values so the following is also valid using the same function as before let numbers Returns i e myFunction numbers This can also be used when calling a constructor with new for example let numbers let thisDate new Date number Merging ArraysAnother useful way to use the spread syntax is to merge arrays For example we can merge two separate arrays into a new one using two spread syntaxes let x let y Returns let newArray x y Similar to before we can combine this with other values and still get the same outcome let x Returns let newArray x Merge ObjectsFinally we can use the spread syntax to merge objects In the below example we merge two objects with key value pairs into one object let obj name John let obj age Returns name John age let newObj obj obj If we try to merge two objects and there is a duplicate key the second object will take precedence and overwrite the first one as shown below let obj name John let obj name Jake Returns name Jake let newObj obj obj And that s how spread syntax work they let us run functions with arrays easily and are good for merging objects and arrays You can find more Javascript tutorials at the bottom of this page	2022-09-04 18:39:50
海外TECH	DEV Community	15+ Array Methods in Javascript	https://dev.to/codewithtee/15-array-methods-in-javascript-1p1m	Array Methods in Javascript What is Array in JS The Array object as with arrays in other programming languages enables storing a collection of multiple items under a single variable name and has members for performing common array operations Declaring arraysWe can declare arrays in two different ways Using new ArrayWith new Array we could specify the elements we want to exist within the array like this const fruits new Array Apple Banana console log fruits length Array literal notationDeclaring with an array literal we specify the values that the array will have If we don t declare any values the array will be empty fruits array created using array literal notation const fruits Apple Banana console log fruits length Javascript Array MethodsHere is a list of the methods of the Array object along with their description forEachThe forEach method executes a provided function once for each array element forEach calls a provided callbackFn function once for each element in an array in ascending index order It is not invoked for index properties that have been deleted or are uninitialized array forEach callback thisObject const array a b c array forEach element gt console log element expected output a expected output b expected output c mapThe Array map method allows you to iterate over an array and modify its elements using a callback function The callback function will then be executed on each of the array s elements array map callback thisObject let arr let modifiedArr arr map function element return element console log modifiedArr The Array map method is commonly used to apply some changes to the elements whether multiplying by a specific number as in the code above or doing any other operations that you might require for your application concatIn JavaScript concat is a string method that is used to concatenate strings together The concat method appends one or more string values to the calling string and then returns the concatenated result as a new string Because the concat method is a method of the String object it must be invoked through a particular instance of the String class array concat value value valueN const array a b c const array d e f const array array concat array console log array expected output Array a b c d e f pushJavascript array push method appends the given element s in the last of the array and returns the length of the new array When you want to add an element to the end of your array use push array push element elementN const countries Nigeria Ghana Rwanda countries push Kenya console log countries Nigeria Ghana Rwanda Kenya popThe pop method removes the last element from an array and returns that value to the caller If you call pop on an empty array it returns undefined Array prototype shift has similar behaviour to pop but applied to the first element in an array array pop const plants broccoli cauliflower cabbage kale tomato console log plants pop expected output tomato console log plants expected output Array broccoli cauliflower cabbage kale spliceThe splice method is a general purpose method for changing the contents of an array by removing replacing or adding elements in specified positions of the array This section will cover how to use this method to add an element to a specific location array splice index howMany element elementN const fruits Banana Orange Apple Mango fruits splice Lemon Kiwi Banana Orange Lemon Kiwi Apple Mango sliceThe slice method returns a shallow copy of a portion of an array into a new array object selected from start to end end not included where start and end represent the index of items in that array The original array will not be modified array slice begin end const animals ant bison camel duck elephant console log animals slice expected output Array camel duck elephant console log animals slice expected output Array camel duck shiftshift is a built in JavaScript function that removes the first element from an array The shift function directly modifies the JavaScript array with which you are working shift returns the item you have removed from the array The shift function removes the item at index position and shifts the values at future index numbers down by one array shift const array const firstElement array shift console log array expected output Array console log firstElement expected output unshiftThe unshift method inserts the given values to the beginning of an array like object Array prototype push has similar behaviour to unshift but applied to the end of an array array unshift element elementN const array console log array unshift expected output console log array expected output Array joinJavaScript array join is a built in method that creates and returns the new string by concatenating all of the elements of the array The join method joins the array s items into the string and returns that string The specified separator will separate the array of elements The default separator is a comma array join separator const elements Fire Air Water console log elements join expected output Fire Air Water console log elements join expected output FireAirWater console log elements join expected output Fire Air Water everyThe every method tests whether all elements in the array pass the test implemented by the provided function It returns a Boolean value array every callback thisObject const isBelowThreshold currentValue gt currentValue lt const array console log array every isBelowThreshold expected output true filterThe filter method creates a shallow copy of a portion of a given array filtered down to just the elements from the given array that pass the test implemented by the provided function array filter callback thisObject const words spray limit elite exuberant destruction present const result words filter word gt word length gt console log result expected output Array exuberant destruction present indexOfThe indexOf method returns the first index at which a given element can be found in the array or if it is not present array indexOf searchElement fromIndex const beasts ant bison camel duck bison console log beasts indexOf bison expected output start from index console log beasts indexOf bison expected output console log beasts indexOf giraffe expected output reduceThe reduce method executes a user supplied reducer callback function on each element of the array in order passing in the return value from the calculation on the preceding element The final result of running the reducer across all elements of the array is a single value array reduce callback initialValue const array const initialValue const sumWithInitial array reduce previousValue currentValue gt previousValue currentValue initialValue console log sumWithInitial reverseThe reverse method reverses an array in place and returns the reference to the same array the first array element now becoming the last and the last array element becoming the first In other words elements order in the array will be turned towards the direction opposite to that previously stated array reverse const array one two three console log array array expected output array Array one two three const reversed array reverse console log reversed reversed expected output reversed Array three two one Careful reverse is destructive it changes the original array console log array array expected output array Array three two one sortThe sort method sorts the elements of an array in place and returns the reference to the same array now sorted The default sort order is ascending built upon converting the elements into strings then comparing their sequences of UTF code units values array sort compareFunction const months March Jan Feb Dec months sort console log months expected output Array Dec Feb Jan March const array array sort console log array expected output Array toStringThe toString method returns a string representing the object array toString function Dog name this name name const dog new Dog Gabby Dog prototype toString function dogToString return this name console log dog toString expected output Gabby atThe at method takes an integer value and returns the item at that index allowing for positive and negative integers Negative integers count back from the last item in the array array at index const array let index console log Using an index of index the item returned is array at index expected output Using an index of the item returned is index console log Using an index of index item returned is array at index expected output Using an index of item returned is findThe find method returns the first element in the provided array that satisfies the provided testing function If no values satisfy the testing function undefined is returned array find function currentValue index arr thisValue const array const found array find element gt element gt console log found expected output someThe some method tests whether at least one element in the array passes the test implemented by the provided function It returns true if in the array it finds an element for which the provided function returns true otherwise it returns false It doesn t modify the array array some callback thisObject const array checks whether an element is evenconst even element gt element console log array some even expected output true	2022-09-04 18:05:05
