We are required to write a JavaScript function that takes in two numbers, say, a and b and returns the total number of prime numbers between a and b (including a and b, if they are prime).For example: If a = 21, and b = 38.The prime numbers between them ... Read More

We are required to write a JavaScript function that takes in a string and a number, say k and returns another string with first k characters removed from the string.For example: If the original string is −const str = "this is a string"and, n = 4then the output should be ... Read More

We are required to write a JavaScript function that takes in two strings and concatenates the second string to the first string.If the last character of the first string and the first character of the second string are the same then we have to omit one of those characters.ExampleThe code ...
