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.
Example 1:
HTML
<!DOCTYPE html><html><head> <script src= </script></head><body> <script> let n = 5 let func = () => { console.log(`This function is called ${n} times \n`) } // The _.times function executes // the above func function n times _.times(n, func); </script></body></html> |
Output:
Example 2:
Javascript
<!DOCTYPE html><html><head> <script src= </script></head><body> <script> let n = 5; let i = 1; let func = () => { for (i; i <= n; i++) { console.log( `It is the function call ${i}`) } } // Calling the function func n times. let c = _.times(n, func); console.log("array returned by times function: ", c) </script></body></html> |
