nextGraphemeClusterBreak

Return the next extended grapheme cluster break in a string after a specified position.

Usage

var nextGraphemeClusterBreak = require( '@stdlib/string/next-grapheme-cluster-break' );

nextGraphemeClusterBreak( string[, fromIndex] )

Returns the next extended grapheme cluster break in a string after a specified position.

var out = nextGraphemeClusterBreak( 'last man standing' );
// returns 1

By default, the function searches for a grapheme cluster break starting from the first index. To specify an alternative starting search index, provide a fromIndex argument.

var out = nextGraphemeClusterBreak( 'last man standing', 4 );
// returns 5

Notes

If string is an empty string, the function returns -1 irrespective of fromIndex.
If an extended grapheme cluster break does not exist after fromIndex, the function returns -1.
Note that fromIndex does not refer to a visual character position, but to an index in the ordered sequence of UTF-16 code units.

Examples

var nextGraphemeClusterBreak = require( '@stdlib/string/next-grapheme-cluster-break' );

var out = nextGraphemeClusterBreak( 'last man standing', 4 );
// returns 5

out = nextGraphemeClusterBreak( 'presidential election', 8 );
// returns 9

out = nextGraphemeClusterBreak( 'अनुच्छेद', 1 );
// returns 3

out = nextGraphemeClusterBreak( '🌷', 0 );
// returns -1
