Parameters / Values
| Parameter / Value | Type | Mandatory | Description | API Version |
|---|---|---|---|---|
| <n> | Number |  | The number of times the fn function should be invoked. If the number is 0, negative or NaN, the function will not be invoked. | 1.1 |
| fn | Function | | The function to invoke. The function is passed a single numeric argument, starting at n-1 on the first iteration, and decrementing with each subsequent iteration, ending at 0 on the final iteration. Note: You can use function.curry() to set parameters for the function. You can also use Hook API to modify arguments or retrieve results when the function is called. | 1.1 |
| context | Object |  | The context in which the fn function should run. Default: The global object. | 1.1 |
Return value
| Value | Type | Notes | API Version |
|---|---|---|---|
| <n> | Number | The number object, eg. so you can chain additional function iterations like so:
| 1.01 |
| <error> | Error | An error, most likely invalid parameters or invalid syntax (eg. not wrapping a primitive value in brackets or using 2 dots). | 1.01 |
Examples
| Code Block | ||||||
|---|---|---|---|---|---|---|
| ||||||
// assuming 4 player game...
(maxPlayers).times( function(num) {
console(num); // 3, 2, 1, 0
// want incremental order?
console(maxPlayers - num - 1); // 0, 1, 2, 3
} ); |
| Code Block | ||||||
|---|---|---|---|---|---|---|
| ||||||
(playerData.length).times(... // wat?!
// always use .forEach on arrays, much better as it
// gives you the value as well as the array index.
playerData.forEach( function(obj, id) {
console("Player "+id+" is in team "+obj.team);
}); |
