JavaScript Mastery from Zero to Hero - Prepare for Coding Interviews - Solution I - How to Repeat a String in JavaScript

The video tutorial explains how to use the repeat method in JavaScript to repeat a string a specified number of times. It demonstrates the implementation of a function that takes a string and a number as arguments and uses the repeat method to return the repeated string. The tutorial also includes a test example with the word 'kangaroo' repeated seven times. Additionally, it discusses alternative solutions using iteration, which might be required in an interview setting.

What is the primary purpose of the repeat method in JavaScript?

• To convert a string to uppercase

• To reverse a string

• To repeat a string a specified number of times

• To find the length of a string

• Lion

• Kangaroo

• Elephant

How many times is the word 'kangaroo' repeated in the example?

• Seven times

• Eight times

• Six times

• Five times

What might an interviewer ask you to demonstrate as an alternative to using the repeat method?

• Using a loop for iteration

• Using a built-in library

• Using a different string method

• Using a different programming language

Why is it important to know alternative solutions like iteration in an interview setting?

• To impress the interviewer with your typing speed

• To show flexibility and problem-solving skills

• To avoid using any built-in methods
