i want to replace space between the string elements with underscore. My expected output is

Use array#map with string#replace

var data = [ 'category','book id','author book','book title','price','publication','publication date' ],
    result = data.map(word => word.replace(' ', '_'));
console.log(result);

let input = [ 'category','book id','author book','book title','price','publication','publication date' ]

let output = input.map( word => word.replace(" ","_") )

// Or for ALL spaces in string : .replace(/ /g, "_")

    arr = arr.map(function(data){
       if(data.split(" ").length>1){
          data.join("_")
       }
     return data;
