Key Takeaways 1. push() method in array simply add the array as an new single entity in the existing array. 2. concat() method help us achieving a desisered output, like merging the two array, but the problems with concat are, It complicated to concat more then one array simultaneously and also It takes extra space and do the merging operation. 3. Despite push and concat we should use spread operator. 4. Intresting methods, isArray(), from() and of()

I love jb sir modern heroes ki jgh old time k heroes k reference dete . Makes me feel like he's someone very simple and remembers old time and cherishes it . Although loving the playlist , thanks for the efforts sir

[@AmitPandey_10]

we can merge multiple arrays using concat as well like spread syntax.. const Array1 = [1,2,3,4,5]; const Array2 = [5,6,7,8,9,10]; const Array3 = [0,0,0]; const Array4 = [1,3,9,19]; const concatAll = Array1.concat(Array2, Array3,Array4) console.log(concatAll)

[@igurutechs2583]

I can relate him as a Web Developer trainer as when at 6:36 he's explaining about Concatenation he's getting unexpected output because sometimes we don't use some methods oftenly so we don't have confidence on it's output and get confused why is that happening, but to keep students motivated and don't let them think Sir ko itna bhi nhi ata we immediately try to show Oh we knew this will occur.. but then we take 1 min break for rechecking and then we debug and explain why that happened 😅😂

[@dnyaneshwarkolhe9959]

Spread operator: My example is tomato bucket, spreading all tomato's on the ground. and rest operator is opposite of it collecting all tomato's on the ground in the bucket. so bucket is array and elements are the tomato's

[@photosofmine3443]

SUMMARRY : 1. Spread operator( ...arrayName) = to create a shallow copy of an array,to join/concatenate arrays,to add elements to an array. 2. .flat(infinity) = to flatten infinity level nested arrays. 3. .from = for converting array-like and objects into arrays. 4. for creating new arrays from a set of values, regardless of how many values are provided or their types.

[@Melodyuniverse-c8c]

Bro all new hero me ... Three dote ku diye hai isse jada bhi de sakte hai

[@thevsringz]

(...) It is the syntax of spread operator. So there can only be three dots as per ES6 in the spread operator. Here Sir used it to copy the elements of dc_heros and marvel_heros into all_new_heros.

Sir include and isArray same work karte hai kya ya phir difference hai dono me

[@namansharma7328]

we are declaring the arrays initially as const, then later on we are changing the values in it. how it this possible.

[@udaytewary3809]

See the data type of array are non primitive it means we will get the reference of the original memory So although they are declare as const "we change the element in the array" i.e arr1[1] = 1 will not give any error But we can't change the array itself that Doing arr1 = arr2 will give error due to const Hope this will.make u understand 😊

[@onlineadda4516]

08:00= Spread Operator,

[@ByteNinjas69]

very helpful.

[@AkbarHosen-yy4pf]

please replay and check this one.. why typeof show its a object ... insted of array .. check bellow const first = "Rohim" const newArray = Array.from(first); (or const newArray = Array.of(first);) console.log(newArray); console.log(typeof newArray); // its shown object as a type .. but we convert it string to array ??? console.log(typeof first);

[@thevsringz]

Dear, Array is not a primitive dataType, it is made with the help of primitive datatypes (Number,String,Boolean etc.) . Therefore Array is considered as Array object of Object datatype. **Note** There are only two types of datatypes in the Javascript i.e. Primitive and Object.

[@MDSoHeL-py2gu]

no

[@sudhanshusharma993]

@@MDSoHeL-py2gu negative index to the slice() method, it counts from the end of the array backwards. So, if you provide -1, it would refer to the last element, -2 would refer to the second-to-last element, example -> 1 - 3 evaluates to -2, so arr1 = array.slice(-2) would include elements starting from the second-to-last element (4) up to the end of the array (5).

@chaiaurcode Facing issue when print the array of flat - "another_array.flat is not a function"

[@thevsringz]

you have to use flat() function, you are just using "another_array.flat" where flat is not a function. When you call a funtion it must be written in proper syntax : function_name() example: you have a function named cars, then it must be written like cars().
