 * Gets the index at which the first occurrence of `value` is found in `array`

 * for equality comparisons. If `fromIndex` is negative, it's used as the offset
 * from the end of `array`. If `array` is sorted providing `true` for `fromIndex`
 * performs a faster binary search.

 * @param {*} value The value to search for.
 * @param {boolean|number} [fromIndex=0] The index to search from or `true`
