Quick JavaScript Crash Course - Modern and Advanced JavaScript - Spread Operators - 2

The video tutorial explains the spread operator in JavaScript, demonstrating its use with arrays, functions, lists, strings, and objects. It highlights how the spread operator can split iterable elements, pass multiple parameters to functions, merge lists, and deconstruct objects, making code more efficient and readable.

What is the primary function of the spread operator when used with arrays?

• To combine multiple arrays into one

• To spread array elements into individual items

• To sort the elements of an array

• To reverse the elements of an array

How can the spread operator be used in functions?

• To return multiple values from a function

• To pass array elements as individual parameters

• To pass multiple parameters as a single array

• To pass a single parameter multiple times

In what context can the spread operator be used with lists?

• To spread list elements into another list

• To remove duplicates from a list

• To merge two lists into one

• To sort the elements of a list

What is a unique feature of the spread operator when used with strings?

• It can change the case of the string

• It can concatenate two strings

• It can reverse the string

• It can split the string into individual characters

How does the spread operator assist in object deconstruction?

• By deleting properties from an object

• By spreading object properties into another object

• By extracting specific properties from an object

• By merging two objects into one

What is the advantage of using the spread operator in object manipulation?

• It allows for easy property addition and merging

• It encrypts object properties

• It automatically sorts object properties

• It prevents property duplication

Which of the following is NOT a use case for the spread operator?

• Deconstructing objects

• Sorting elements of a list

• Combining multiple objects
