从字符串数组中剪切第一个单词并存储在新变量中

我现在得到的是这样一个数组:

['Alica Brereton,Marijuana,9.18,50',
  'William Kotai,ecstasy,19.12,20',
  'Joel Forro,heroin,91.16,5',
  'David Ernest,Methamphetamine,108.78,5',
  'David Ernest,cocaine,80,2',
  'Joel Forro,ecstasy,19.12,10',
  'Gabriella Hyde,Marijuana,9.18,10',
  'Gabriella Hyde,Methamphetamine,108.78,8',
  'Marijuana,9.18,10'
]

我想在每个字符串的开头剪切名称,并存储在一个新的变量中,所以我会有这样的内容:

['Alica Brereton',
  'William Kotai',
  'Joel Forro',
  'David Ernest',
  'Joel Forro',
  'Gabriella Hyde'
]

我正在处理一个文本文件这里是我的当前

code: 
const fs = require("fs");
const data = fs.readFileSync("data.txt").toString();
const lines = data.split("\n");

let customerKeys = lines[0].replace("customer", "Total Price");
lines.shift();
console.log(customerKeys);
console.log(lines);

let array = lines.filter((str) => {
  return str !== "";
});
let arrNoSpaces = array;

console.log(arrNoSpaces);
arrNoSpaces[6].replace("Gabriella Hyde,", "");
var GabriellaExtra = arrNoSpaces[6].replace("Gabriella Hyde,", "");
console.log(GabriellaExtra);

arrNoSpaces.push(GabriellaExtra);
console.log(arrNoSpaces);
arrNoSpaces.splice(-3, 1);

console.log(arrNoSpaces);
