Underscore.js _.times() Function

0 0 1 minute read

Underscore.js is a JavaScript library that makes operations on arrays, string, objects much easier and handy.
The _.times() function in underscore.js is used to call the function a particular number of times i.e. execution of a function(f) “n” number of times.

Note: It is very necessary to link the underscore CDN before going and using underscore functions in the browser. When linking the underscore.js CDN link, the “_” is attached to the browser as a global variable.

Syntax:

_.times(n, iteratee)

Parameters:It takes following parameters:

n: It tells how many times a function is needed to be executed.
iteratee : It is a function that is to be invoked n times.

Return Value: It produces an array of returned values and this array is returned by the function.
