how to convert nested object to array ? const student = { "name": "Nageswaran", "age": 23, "degree": "BBA", "marks": { "english": 5, "science": 10 } }; output should be ["name", "Nageswaran", "age", 23]

thanks

arr1:[1,2,3] arr2:[1,2,3,4]

Negating array with ! character will coerce the array into Boolean. Since arrays are considered truthy so negating it will return false.

23

Good video. Suppose it is two dimensional array. And the keys to be the first row of the array. How to go about it?

i just checked ur channel u r giving amazing info will definitely watch FE series keep helping us...

ｐｒｏｍｏｓｍ 🎶

what if I want object key like name, age, country etc. not any integers like 0,1,2 ....?

Thanks 👍

Superb explanation, the doubt I was searching was clarified clearly. Thank you

Got stuck on the dummiest step. Your video helped me really. Thank you so much!

false

Output will be 10

Output will be false. Null is falsy, !null is true, !true is false.

10 due to hoisting

sum function accepts two arguments a & b. But we are passing 2 + '3' that is 23 now a is 23 and b is undefined In this case, output will be 23undefined

Error: you are sending only one argument that is 23 and the sum function requires 2 arguments at a time.

23

It will give an error because in argument you're passing 1 value and in parameter 2 values are required.

23

1,2,4

1 2 4 5

1 2 4

3

🤓

The output is the Babers from 1 to 4 without 3(excluded): 1 2 4

1,2,4

Output will be 1 2 4 Continue statement will skip the iteration when i is 3 and the loop continues executing.

Output will be false. ''is falsy, !'' returns true, !true return false
