JavaScript: Bigger elements in an array

JavaScript Function: Exercise-19 with Solution

Find Elements Larger Than Number

Write a JavaScript function that returns array elements larger than a number.

Sample Solution-1:

JavaScript Code:

// Define a function named BiggerElements that returns a filtering function
function BiggerElements(val) {
   // Return a filtering function that checks if the array element is greater than or equal to the given value (val)
   return function(evalue, index, array) {
      return (evalue >= val);
   };
}

// Create an array named result by filtering elements greater than or equal to 10 using BiggerElements(10)
var result = [11, 45, 4, 31, 64, 10].filter(BiggerElements(10));

// Log the filtered array to the console
console.log(result); 

Output:

[11,45,31,64,10]

Sample Solution-2:

JavaScript Code:

// Function to filter array elements larger than a given number
function elementsLargerThan(arr, threshold) {
    // Use the Array.prototype.filter method to filter elements
    const largerElements = arr.filter(element => element > threshold);
    return largerElements;
}

// Example usage:
const inputArray = [1, 5, 8, 10, 15, 20];
const thresholdNumber = 8;
const resultArray = elementsLargerThan(inputArray, thresholdNumber);

// Log the result to the console
console.log(resultArray);

Output:

[10,15,20]

• Write a JavaScript function that filters an array to return elements larger than a given threshold without using the filter() method.
• Write a JavaScript function that iterates through an array using a loop and returns elements greater than a specified number.
• Write a JavaScript function that finds elements larger than a given number and then sorts the resulting array in ascending order.
• Write a JavaScript function that uses recursion to find and return all array elements that are greater than a specified value.
