Javascript: assign value on arrays data

Here is my code

function gotData(data){
        result = data.val() 
        const urls_kws = Object.keys(result)
                    .filter(key => result[key].last_res > 10)

        var keywords = urls_kws;

        console.log(urls_kws)

        for(var i=0;i<keywords.length;i++) {
        keywords[i] = keywords[i].replace(/-/gi, " " )
    }

}

Result is

[ '7-skinfood-gold-caviar-collagen-cream',
  'beauty-credit']

But when i move console.log(urls_kws) to below

function gotData(data){
        result = data.val() 
        const urls_kws = Object.keys(result)
                    .filter(key => result[key].last_res > 10)

        var keywords = urls_kws;

        for(var i=0;i<keywords.length;i++) {
        keywords[i] = keywords[i].replace(/-/gi, " " )
    }

        console.log(urls_kws)
}

Result is

[ '7 skinfood gold caviar collagen cream',
  'beauty credit']

My question is how can i keep value on urls_kws because i need to use both of var urls_kws(with -) and keywords(without -)
