Convert snake-case to camelCase
function snakeToCamel(s){
return s.replace(/(\-\w)/g, function(m){return m[1].toUpperCase();});
}or as more readable code
var snakeCaseString = 'lorem-ipsum';
var find = /(\-\w)/g;
var convert = function(matches){
return matches[1].toUpperCase();
};
var camelCaseString = snakeCaseString.replace(
find,
convert

Btw, snake case looks_like_this, your example is for converting hyphen separated words into camel case.
To do snake case, the regex in your example should look like this:
/(_\w)/g

Why do you need the () capturing group? It works without that too:
value.replace(/_\w/g, function(m) {
return m[1].toUpperCase();
});

@lethys is totally right. That is a kebab-case regex.

Shorter:
value.replace(/_\w/g, (m) => m[1].toUpperCase() );

Actually you do need the capturing group, because you want to omit the underscore in the result:
value.replace(/_(\w)/g, (m => m[1].toUpperCase()));
