Question

Aryan Kumar · Answer

There are a few ways to remove a specific item from an array in JavaScript.
Method 1: Using the indexOf() method
The indexOf() method can be used to find the index of an item in an array. Once you have the index of the item you want to remove, you can use the
splice() method to remove it from the array.
The splice() method takes three arguments:
The index of the item you want to removeThe number of items you want to removeA new array of items to replace the removed items
For example, the following code removes the item with the index 1 from the array
myArray:
const myArray = [1, 2, 3, 4];
const index = myArray.indexOf(2);
myArray.splice(index, 1);
console.log(myArray); // [1, 3, 4]
Method 2: Using the for loop
The for loop can be used to iterate through the array and remove the item you want to remove.
The for loop takes three arguments:
The starting indexThe ending indexA function to be executed for each item in the array
For example, the following code removes the item with the value 2 from the array
myArray:
const myArray = [1, 2, 3, 4];
for (let i = 0; i andlt; myArray.length; i++) {
  if (myArray[i] === 2) {
    myArray.splice(i, 1);
    break;
  }
}
console.log(myArray); // [1, 3, 4]
Method 3: Using the while loop
The while loop can be used to iterate through the array and remove the item you want to remove.
The while loop takes two arguments:
A condition that must be true for the loop to continueA function to be executed for each item in the array
For example, the following code removes the item with the value 2 from the array
myArray:
const myArray = [1, 2, 3, 4];
var i = 0;
while (i andlt; myArray.length) {
  if (myArray[i] === 2) {
    myArray.splice(i, 1);
    break;
  }
  i++;
}
console.log(myArray); // [1, 3, 4]
