Answer:
replace()
Explanation:
The history object in javascript corresponds to browsing history.
It has the following methods for navigating through the history list:
back(): Go back in the history list
forward(): Go forward in the history list
go() : Navigate to the currently pointed url in the history list. It takes a parameter which can either be a numeric index or a string which is matched with the history list content.
replace() is not a method in the history object.
Instead of having to write multiple pieces of code for different outcomes, you can use an elseif statement and make your code easier to read and easier to understand.
You can style and structure with it so it’s either one of those
Answer:
integer
Explanation:
The expression can be implemented as follows:
x <- 4L
class(x)
Here x is the object. When this expression is executed in R, the class "integer" of object 'x' is determined by the class() function. R objects for example x in this example have a class attribute determines the names of the classes from which the object inherits. The output of the above expression is:
"integer"
Here function class prints the vector of names of class i.e. integer that x inherits from. In order to declare an integer, L suffix is appended to it. Basically integer is a subset of numeric. If L suffix is not appended then x<-4 gives the output "numeric". Integers in R are identified by the suffix L while all other numbers are of class numeric independent of their value.
