var zeroTo = require( '@stdlib/array-base-zero-to' );Generates a linearly spaced numeric array whose elements increment by 1 starting from zero.
var arr = zeroTo( 6 );
// returns [ 0, 1, 2, 3, 4, 5 ]If n <= 0, the function returns an empty array.
var arr = zeroTo( 0 );
// returns []
arr = zeroTo( -1 );
// returns []If n is a non-integer value greater than zero, the function returns an array having ceil(n) elements.
var arr = zeroTo( 5.1 );
