The midIndexOf method returns the first index at which a given element can be found in the array, or -1 if it is not present.

Specially, this method will search from the middle index, and go to left and right to find target element.

syntax

1midIndexOf(array, searchElement, startIndex);

startIdex is optional, and default is half the length of the array.

example

1import midIndexOf from 'mid-index-of';
2
3midIndexOf(['a', 'b', 'c', 'd', 'e', 'f'], 'e', 1);
4// result: 1
5// Actually, it will search with snake path: b -> c -> a -> d -> e
