The concat() method is used to merge two or more arrays.The unshift() method adds one or more elements to the beginning of an array.The shift() method removes the first element from an array.The pop() method removes the last element from an array.The push() method adds one or more elements to the end of an array.In addition to the splice() and slice() methods, TypeScript has several other useful array methods: In the second part of this example, the Array.slice() method is used to create a new array with elements from index 2 (the number 6) up to index 4 (the number 4), not including index 4. The removed element is returned as an array with a single element. In the first part of this example, the Array.splice() method is used to remove one element (the element at index 2) and add one new element (the number 6) to the array. Here’s an example that shows the differences between the two methods: let arr = The splice() method can be used to add elements to an array, while the slice() method is used to create a new array from an existing array. The splice() method returns the removed elements as an array, while the slice() method returns a new array. The splice() method modifies the original array, while the slice() method does not. In this example, the Array.slice() method is used to create a new array with elements from index 2 (the number 3) up to index 4 (the number 5), not including index 4. Here’s an example of how to use the Array.slice() method: let arr = If no parameters are specified, the entire array is returned.
The first parameter specifies the start index, and the second parameter specifies the end index (not included in the new array). The Array.slice() method is used to create a new array from a portion of an existing array. In this example, the Array.splice() method is used to remove one element (the element at index 2) and add one new element (the number 6) to the array. Here’s an example of how to use the Array.splice() method: let arr = Ĭonsole.log(arr) // Output:
