JavaScript: Replace all the numbers with a specified number of a given array of integers
JavaScript Basic: Exercise-95 with Solution
Write a JavaScript program to replace all numbers with a specified number in an array of integers.
Visual Presentation:
Sample Solution:
JavaScript Code:
// Function to replace a specified element in an array with a new value
function array_element_replace(arr, old_value, new_value) {
for (var i = 0; i < arr.length; i++) {
// Check if the current element is equal to the old value
if (arr[i] === old_value) {
arr[i] = new_value; // Replace the old value with the new value
}
}
return arr; // Return the modified array
}
// Example usage
num = [1, 2, 3, 2, 2, 8, 1, 9]; // Original array
console.log("Original Array: " + num);
console.log(array_element_replace(num, 2, 5)); // Replace 2 with 5 in the array
Output:
Original Array: 1,2,3,2,2,8,1,9 [1,5,3,5,5,8,1,9]

Flowchart:
ES6 Version:
// Function to replace all occurrences of a specified value in an array
const array_element_replace = (arr, old_value, new_value) => {
// Iterate through the array
for (let i = 0; i < arr.length; i++) {
// Check if the current element is equal to the old value
if (arr[i] === old_value) {
arr[i] = new_value; // Replace with the new value
}
}
return arr; // Return the modified array
};
let num = [1, 2, 3, 2, 2, 8, 1, 9]; // Example array
console.log("Original Array: " + num);
console.log(array_element_replace(num, 2, 5));
