JS SPLICE REMOVE ELEMENT HOW TO

The example below depicts how to make use of the reduce() method to eliminate all numbers that are less than 10 from a given array. The reduce() method gives us another solution to remove elements from an array. The example below demonstrates how to remove all strings whose length is less than 6 from a given array of words: const words = [Ĭonst result = words.filter((word) => word.length >= 6) It takes a callback function as an argument and returns a new array with all of the elements that pass the given test.įor example, if you wanted to remove all of the elements from an array called myArray that are greater than 10, you could use the following code: let filteredArray = myArray.filter(num => num = 10) Ī new array is created and returned by the filter() method while the original array is intact. The filter() method is a powerful tool for removing specific elements from an array based on a given condition. Let’s see the practical example below for more clarity: const numbers = Ĭonsole.log(numbers) // Using the filter() Method

removedElements: The splice() method returns the removed elementsįor instance, if you wanted to remove the third, fourth, and fifth elements from an array called myArray, you could use the following code: myArray.splice(2, 3).

deleteCount: The number of elements that you want to delete.startIndex: The position to start removing elements.The syntax for the splice method is as follows: removedElements = array.splice(startIndex, deleteCount) Show a Custom Context Menu on Right Click Programmatically Disable/Enable a Text Input Get an array of dates between 2 given datesĬonvert a Map object to JSON and vice versa Sorting an Array of Objects by Date Property Truncate the time portion of a date string Get current date time in yyyy/MM/dd HH:mm:ss formatĢ Ways to Convert a String into a Date ObjectĬonvert Timestamp to Date Time and Vice Versa Get the Key of an Object Property by Its ValueĬreate/Access Object Properties with Variable KeysĬhecking if a Key/Value Exists in an ObjectĬreate an Object from Arrays of Keys and ValuesĬonvert an Object to a Query String and Vice Versa Pass a JavaScript Array within a Query String Pass an Array to a Function as multiple Arguments Remove elements that occur in one array from another Remove all occurrences of a value from an arrayĬheck if an array contains a given objectĬonvert an Array to an Object in JavaScriptįind elements in array A but not in array B Update/Replace a Specific Element in an Array How to append/prepend/insert elements to an array
