Reference
syntax
eachArg(arr, start, callback(value, index, ...extra): any, ...extra): void;
Iterates over the array, string or array-like arr starting from the start index. The callback function will be called for every value in the array, with the value itself, the index of the current item and any extra argument passed to eachArg function.
If a negative start index is provided the iteration will start from X number of items counting from the last item in the input array-like.
If the callback returns a truthy value the iteration will stop.
Any extra argument passed to eachArg function will be passed down to the callback function.
The callback function inherits the this value form the eachArg function call. If you need a specific value inside the callback, call eachArg using it's call method.
eachArg.call(thisArg, arr, start, callback, ..extra);
example
import eachArg from "each-arg";
eachArg([1, 2, 3, 4, 5], 1, (value, index, num) => {
console.log(value + " >> " + (index + num));
return index === 3;
}, 100);
2 >> 101
3 >> 102
4 >> 103
