Question

Make sure to verify if all values are contained within an array by utilizing JavaScript or TypeScript

These are the two arrays I'm working with. My goal is to ensure that every value in ValuesToBeCheckArr is present in ActualArr. If any values are missing from ActualArr, the function should return 0 or false. Additionally, there is an operator variable that can have a value of either AND or OR. I have successfully implemented a solution for the OR operator but am struggling to come up with one for the AND operator.

ActualArr = [1,2,3,4,5,6,7,21,25,35,50,132];
ValuesToBeCheckArr = [2,3,50,132];
Operator = AND/OR

if(Operator == AND) {
   //check every value of ValuesToBeCheckArr should be in the ActualArr
} else if(Operator == OR) {
   //check at least one value of ValuesToBeCheckArr should be in the ActualArr
   const checkIncluded = (arr1, arr2) => arr1.some(item => arr2.includes(item));
   const isIncluded1 = checkIncluded(["1", "2"], ["3"]) // true
}

Answer №1

Using the Operator == AND

==> you can achieve this by utilizing Array#every in conjunction with Array#some as shown below

const ActualArr = [1,2,3,4,5,6,7,21,25,35,50,132];
const ValuesToBeCheckArr = [2,3,50,132];

const result = ValuesToBeCheckArr.every(v => ActualArr.some(a => v == a))
console.log(result);

The every() method evaluates whether all elements in the array satisfy the criteria specified by the provided function. It returns a Boolean value.

The some() method assesses if at least one element in the array meets the conditions set by the supplied function. It returns true if there is an element in the array for which the provided function returns true; otherwise, it returns false. The original array remains unchanged.

This code snippet demonstrates the functioning of a checkInclusion function that evaluates whether one array is included in another based on a specified operator.

function checkInclusion(actualArr,checkArr,operator){
 let isIncluded = operator === "AND"?
 actualArr.every(item=>checkArr.includes(item)):
 actualArr.some(item=>checkArr.includes(item))
 return isIncluded;
}


console.log(checkInclusion(["1", "2","3"], ["1","3"],"AND"));
console.log(checkInclusion(["1", "2","3"], ["1","3"],"OR"));

To convert the .some to .every, you must modify the code. This change will ensure that every element in the array meets the specified condition:

NewArr = [10,20,30,40,50,60,70,210,250,350,500,1320];
ValuesToBeCheckedArray = [20,30,500,1320];
Operator = AND/OR

if(Operator == AND) {
   //check whether all ValuesToBeCheckedArray elements are present in NewArr
   const checkAllIncluded = (arr1, arr2) => arr1.every(item => arr2.includes(item));
   const isIncludedNow = checkAllIncluded(ValuesToBeCheckedArray, NewArr)
} else if(Operator == OR) {
   //check if at least one value from the ValuesToBeCheckedArray is in NewArr
   const checkAnyIncluded = (arr1, arr2) => arr1.some(item => arr2.includes(item));
   const isPresent = checkAnyIncluded(["10", "20"], ["30"]) // true
}

   const isPresent = checkAnyIncluded(["10", "20"], ["30"]) // true
}
