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}`)
}
}
let c = _.times(n, func);
console.log(
"array returned by times function: ", c)
</script>
</body>
</html>
