Modern JavaScript from the Beginning - Second Edition - Anagram Algorithm

The video tutorial explains anagrams, demonstrating how to create a function to check if two strings are anagrams. It covers setting up a project with necessary files, writing tests using Jest, and implementing the function using character maps. The tutorial also includes running and debugging tests, and concludes with a preview of the next video on DOM elements.

What is an anagram?

• A word that starts with the same letter as another word.

• A word that rhymes with another word.

• A word formed by rearranging the letters of another word.

• A word that has the same number of syllables as another word.

What is the purpose of the initial test for the anagram function?

• To check if the function returns a string.

• To verify if the function is defined.

• To confirm the function returns a number.

• To ensure the function returns a boolean.

What is a character map in the context of the anagram function?

• A map that stores the ASCII value of each character.

• A map that stores the index of each character in a string.

• A map that stores each character and its frequency in a string.

• A map that stores the length of each string.

Why do we compare the lengths of the character maps in the anagram function?

• To confirm both strings have the same number of words.

• To ensure both strings are of the same length.

• To check if both strings have the same number of vowels.

• To verify if both strings start with the same letter.

What is the next topic to be covered after the anagram function?

• Working with DOM elements in Node.js.

• Creating a new anagram function.

• Building a web server with Node.js.

• Testing functions with Jest.
