index.js Examples. Splicing won't be as fast as the other two methods because it will return the removed elements as an array.
The indexOf method returns the first index at which the element can be found or -1 if the element is not in the array.
This method is mostly used to replace elements at or starting from any given index but this replace can in fact be used in ways to make it work like just addition or just removal as well.

The solution you proposed consisted of two nested loops: First loop iterates n time. Using array literal replaceAll () Parameters The replaceAll () method takes a single parameter. First use The toString () method returns a string with array values separated by commas. We can use the splice method to remove an array elements by index.. However, the replace () method will only replace the first occurrence of the specified character. The syntax is:
Add a Class to an HTML Element Using className. Note that these methods all mutate the original array.

Using bracket notation, change the value of the element at the specific index.
. If the element is present in both array, then push this element to the arr array.
