/**
* Returns the index of the first truthy element in a strided array.
*
* ## Notes
*
* -   If unable to find a truthy element, the function returns `-1`.
*
* @private
* @param {PositiveInteger} N - number of indexed elements
* @param {Object} x - input array object
* @param {Collection} x.data - input array data
* @param {Array<Function>} x.accessors - array element accessors
* @param {integer} strideX - stride length
* @param {NonNegativeInteger} offsetX - starting index
* @returns {integer} index
*
* @example
* var toAccessorArray = require( '@stdlib/array/base/to-accessor-array' );
* var arraylike2object = require( '@stdlib/array/base/arraylike2object' );
*
* var x = [ 0.0, 0.0, 3.0, 0.0, 4.0, 0.0, -1.0, -3.0 ];
*
* var idx = gindexOfTruthy( x.length, arraylike2object( toAccessorArray( x ) ), 1, 0 );
* // returns 2
