Scope of variables in JS/nodejs

Question

.content and noiseWords are the arrays which consist of strings. My aim is to remove noiseWords from content. Both content and noiseWords are not global variables. Can I access noiseWords in the word()? Is line 4 correct? If not, then how can I access noiseWord inside word()?

word(content){
// this function remove noiseWords from the Content 
//and then return the content

noiseWords.split(/\s+/).map((w) => 
normalize(w));//line4    

 }

addNoiseWords(noiseWords){
//this function consists noisewords
}

Can I access noiseWords in the word()?

No

Is the line 4 correct? If not then how can I access noiseWord inside word()? I have mentioned "line 4" in the code.

You need to pass that array as parameter in function word(), for example:

function word(content, noiseWords){...}

or pass an object with those values:

function word(obj){
    var {content, noiseWords} = obj;
    .
    .
    .
}

or pass an array with those values:

function word(array){
    var [content, noiseWords] = array;
    .
    .
    .
}

I am not supposed to do so. I can't use word(content,noiseWords). DO you have any other idea?

function word(obj){ var {content, noiseWords} = obj; . . } // How can I access noiseWords inside word since noiseWord is not a global varibale? Also I cant change the parameters of word. It has to be word(content).
