JavaScript Array Remove an Element Remove Array element by Index. First we will see an example were we will remove array element by its index. For this we can define a generic function removeByIndex() . In above code we used javascript splice() method to remove element at an index.splice() method takes two argument. First is the index at which you want to remove element and second is number of elements to be removed. In our case it is 1. To test the above code lets define a simple array and remove one of the element.Also you may want to define removeByIndex method with an array so that you call it directly. For example, in following example, we have define an array test and its method removeByIndex().o test the above code lets define a simple array and remove one of the element.

Text formatting This chapter introduces how to work with strings and text in JavaScript. JavaScript's String type is used to represent textual data. It is a set of elements of 16-bit unsigned integer values. Each element in the String occupies a position in the String. The first element is at index 0, the next at index 1, and so on. The length of a String is the number of elements in it. You can create strings using string literals or string objects.

- For that, you need a different data type: a list of strings where each string corresponds to a word. .split() is the method to use: .split() splits mary on whitespce, and the returned result is a list of words in mary.

Removing the first X number of characters from a string in Excel and Google Spreadsheets There is a very nifty function you can use for this: RIGHT(). RIGHT() returns the last X characters of a certain string, based on a number of characters you specify. Like: RIGHT(text,num_chars). Say you want to remove the first 2 characters from a string in cell B1 you can use: =RIGHT(B1,LEN(B1)-2).Or in more general terms:=RIGHT(B1,LEN(B1)-[number of characters to remove]). LEN(B1) returns the length of the string in cell B1: 12 letters. 2  It then subtracts 2, in order to leave out the first 2 characters: 12-2=10. 3  Then RIGHT() takes the last 10 letters from the string and returns: marketsize. 4  In effect, this has removed the first 2 characters of the string.
