Description

This RFC proposes adding support for invoking a callback for each (visual) character of a string, while iterating from right-to-left.

Signature:

forEachRight( str, clbk[, thisArg] )

where clbk (similar to @stdlib/utils/for-each-right) is provided

• value: visual character
• idx: starting character index
• str: input string

Package: @stdlib/string/for-each-right
Alias: forEachRight

Related Issues

Will require iterating over grapheme cluster breaks. See @stdlib/string/reverse for such an example.

• @stdlib/string/base/for-each-code-point-right

Hi @kgryte,
Hope all is well! I'd be interested in working on this RFC, if it's still available. Could you please assign me to it?
Thanks,

[kgryte]

@AhmedKhaled590 Sure thing. Please start by working on @stdlib/string/base/for-each-right. If that goes well, we can move on to the others.
