Let say I have an array:-
var arr = [0,1,2,3,4]
I need to pass only "1" and "4" to function below
function func1(onlyArray){
//Do Stuff...
}
I have tried both but both also dont work
func1(arr[1,4])
func1(arr[[1],[4]])
Can anyone show me the right way or give me some keyword?
You can use this:
func([arr[1], arr[4]])
We are taking the elements at index 1 and 4 of the array arr and creating a new array with those elements. Then we pass that newly created array to func.
If you need a single array instead of 2, use this:
var arr = [0,1,2,3,4];
function func1(onlyArray){
//Do Stuff...
console.log(onlyArray); // [1, 4]
}
func1(arr.filter((item,index) => index === 1 || index === 4));
[arr[1], arr[4]] is much simpler, why not just use that ?
So using your array:
var arr = [0,1,2,3,4];
and your function:
function myFunction(newArr){
//Do stuff
console.log(newArr);
};
You can wrap the array indexes you want to use inside of their own array when you call the function, like the following:
myFunction([arr[1], arr[4]]); //Output is [1, 4]
func(arr[1], arr[4])func([arr[1], arr[4]])
