将带有变量的字符串数组推送到循环内的数组

Question

Could someone help me on below code? How do I push an array with variables?

function theBeatlesPlay(musicians, instruments) {
  var array = []
  var i;
  var m = ms[i];
  var it = its[i];
  var string = "`${m}` plays `${it}`";

  for (i = 0; i < 4; i++) {
    array.push(string)
  }

  return array
}

Thanks a lot in advance!

Answer 1

Most of what you did should be placed inside the for loop. Like this:

function theBeatlesPlay(musicians, instruments){
    var array = [];
    for(var i=0; i<musicians.length; i++){
        var m = musicians[i];
        var it = instruments[i];
        var string = `${m} plays ${it}`;
        array.push(string);
    }
    return array;
}

Also note the syntax for the template literal: the whole string is delimited by backticks, and you should not have those double quotes.

Instead of iteration to 4, use the actual length of the array.

function theBeatlesPlay(musicians, instruments){
    var array = []
    var i;
    for(i=0; i<4; i++){
        var m = ms[i];
        var it = its[i];
        var string = "`${m}` plays `${it}`";
        array.push(string)
    }
    return array
}

yes It is pseudo-code and It's actually something like this;

 var ms = ["aa", "bb", "cc"]; var its = ["dd", "ee", "ff"]; function funct(ms, its){ var array = [] var i =0; for(i=0; i<4; i++){ var m = ms[i]; var it = its[i]; var string = "${m} plays ${it}"; array.push(string) } return array }
