Remove an Element from an Array

Remove an Element from an Array

To remove an element from an array, you can use the filter method or manually iterate through the array.

Algorithm:

1. Use the filter method to create a new array without the specified element.
2. Alternatively, iterate through the array and remove the element manually.
3. Return the modified array.

Example:

function removeElement(arr, elem) {
    return arr.filter(item => item !== elem);
}

// Example usage
console.log(removeElement([1, 2, 3, 4, 5], 3)); // Output: [1, 2, 4, 5]
console.log(removeElement(["apple", "banana", "orange"], "banana")); // Output: ["apple", "orange"]

This method has a time complexity of O(n), where n is the length of the array.
