do <something> N times (declarative syntax)
javascript, jquery, underscore.js
Solution
This answer is based on `Array.forEach`, without any library, just native vanilla.
To basically call `something()` 3 times, use:
[1,2,3].forEach(function(i) {
something();
});
considering the following function:
function something(){ console.log('something') }
The output will be:
something
something
something
To complete this questions, here's a way to do call `something()` 1, 2 and 3 times respectively:
It's 2017, you may use ES6:
[1,2,3].forEach(i => Array(i).fill(i).forEach(_ => {
something()
}))
or in good old ES5:
[1,2,3].forEach(function(i) {
Array(i).fill(i).forEach(function() {
something()
})
}))
In both cases, the output will be
The output will be:
something
something
something
something
something
something
(once, then twice, then 3 times)
Problem
Is there a way in Javascript to write something like this easily: ``` [1,2,3].times do { something(); } ``` Any library that might support some similar syntax maybe? Update: to clarify - I would like `something()` to be called 1,2 and 3 times respectively for each array element iteration
