The invoke
function from the underscore library in JavaScript is used for invoking a method on each item in a collection of objects. Here's how to use it:
index.tsx45 chars2 lines
collection
: An array (or any other collection) of objects on which the method needs to be invoked.methodName
: The name of the method that needs to be invoked on each object of the collection.*arguments
: Any additional arguments to pass to the invoked method.Here's an example of how to use invoke
to invoke the toString
method on each object in an array:
index.tsx97 chars3 lines
In this example, the toString
method is invoked on each number in numbers
using invoke
. The resulting array strings
contains the string representation of each number in numbers
.
You can also pass additional arguments to the invoked method. Here's an example of how to use invoke
to invoke the slice
method with additional arguments on each string in an array:
index.tsx128 chars3 lines
In this example, the slice
method is invoked on each string in strings
with additional arguments 2
and 4
using invoke
. The resulting array slicedStrings
contains the sliced substrings of each string in strings
.
