how could set multi separator of “_.truncate” of Lodash?

how can I separate by “,” or “-” or ” ” ?

    let _r = _.truncate('hi-diddly-ho there, neighborino', {
          'length': 16,
          'separator': /,- +/
        });
        console.log(_r);   //need output: hi
    
    let _r = _.truncate('hi!diddly ho there, neighborino', {
          'length': 16,
          'separator': /,- +/
        });
        console.log(_r);   //need output: hi!diddly
    
    let _r = _.truncate('hi!diddly!ho,there, neighborino', {
          'length': 16,
          'separator': /,- +/
        });
        console.log(_r);   //need output: hi!diddly!ho

if setting "/,- +/" is not working, what should I do?

Answer

Your regular expression is basically saying, “match ,- followed by at least one space”.

^{Check it on Regex101}

This would match ",- ", for example.

What you want is a character group of ,, - and space (note that you need to escape - there):

/[,- ]/

^{Check it on Regex101}
