Javascript

1. Write a function which receives four arguments (array, start, end, delimiter). Copy the array values from the start to end index separated by delimiter\'s value. function([1,2,3,4],1,3,'*') // returns 2*3*4 as string

2. Write a function to change the case of all the characters in string based on their position which matches the value of the pos parameter passed to function(str, pos [even|odd]). Example: function(‘abCd’, ‘odd’) // returns Abcd

3 Write a function which receives two arguments (array, oddOrEven) based on the value of oddOrEven (odd or even value) the function will return the sum of all the array elements that matches the type of oddOrEven value. function([1,1,2,3,4],11) // returns 5 (which is the sum of all odd numbers)

function joinString(array, start, end, delim) {
  if(start <= end) {
    s = array[start]
    i = start + 1
    while(i <= end) {
      s = s + delim + array[i]
      i++;
    }
    return s
  }
}
console.log(joinString([1,2,3,4],1,3,'*'))

Write a function (in Javascript) called longestMorseCodeWords which takes in an array of strings. The output of longestMorseCodeWords should be an array of the strings that were passed in, but ordered by the length of their Morse Code equivalent in descending order. If the length of Morse Code is equal, order the words alphabetically.For convenience, the full table for the 26 letters of the English alphabet is given below: [".-","-...","-.-.","-..",".","..-.","--.","....","..",".---","-.-",".-..","--","-.","---",".--.","--.-",".-.","...","-","..-","...-",".--","-..-","-.--","--.."] let words = ["gin", "zen", "gig", "msg"] longestMorseCodeWords(words) The Morse...

JavaScript Write a function called "first" that takes in two arguments - the first is an argument called arr that is an array of numbers, the second is an optional number argument called num(hint: you'll need a default value - look back at the slides). If "num" was not passed in (since it's optional), the "first" function will return an array containing the first item of the array. If a value for "num" was given, the "first" function will return...

2 Write a function named equivalentArrays that has two array arguments and returns 1 if the two arrays contain the same values (but not necessarily in the same order), otherwise it returns 0. Your solution must not sort either array or a copy of either array! Also you must not modify either array, i.e., the values in the arrays upon return from the function must be the same as when the function was called. Note that the arrays do not...

Define a function in Javascript named secondHighest which accepts an array of numbers, and returns the second highest number from the array. If the highest value occurs more than once, then it is also the second highest (see example). Assume the input array will always have length at least two (so there is always a second highest value). The original array must NOT be modified by this function. Example secondHighest([5,3,8,6,2,7,4]) must return 7, and secondHighest([5,3,8,6,2,7,8]) must return 8. I have...
