Not only deleting is the method to remove unwanted elements. There are many other helpful methods to clean array values.
- Pop: Help in the removal of items from the end
- Shift: Help in the removal of items from the start
- Splice: Help in the removal of items from the middle
- Filter: Help in the programmatic removal of items
For this, you must use the pop method. It helps to remove the element from the end. Moreover, it may also help to return the items and update the new length.
Removing Array Items By Value Using Splice:
You may use this method when you only want to remove one item. In comparison, you have to remove many items at a time. Then there may be a problem in matching the criteria.
When you remove the element, there is an automatic increase in the index. So, it may easily skip the next matched item.
Suppose you don’t want to skip the next matched item. Then make sure to decrease the index value of the array.
Using the Array filter Method to Remove Items By Value:
- Current value
- Current array index
- Full array
Make sure to find the current array where matched values are present. So, you may keep the new array untouched.
The Lodash Array Remove Method:
Maybe you are facing some challenging situation, or your matter is complex. In that case, you may use the Lodash method. This method helps to handle many array sets.
Making a Remove Method:
You may create a new method using the help of the utility library. So, you may get the method in which the first parameter is the targeted array.
Though it is the simplest method, so, it uses simple values such as numbers. You may make another helpful method, but it is the best among all others.
Explicitly Remove Array Elements Using the Delete Operator
You have the option to use a delete operator for the removal of specific elements:
This method doesn’t damage the length of the array. Moreover, it doesn’t have any effect on the index of the element. Using this method, you may thin the array. It is the best way to keep undefined all the deleted items instead of removal.
Maybe you have to remove all the items from the array. For this, you may choose any of the methods from several methods. The only easier method for this is the setting of any array variable to an empty array.
Maybe this method create an issue if there is a reference for the variable. Obviously, the reference can’t change and have the original value. So, it may cause a big bug when you have to initialize array in java.
So, you may use any of these methods and remove unwanted items from the group. All these methods are easier and more consistent!
