未捕获的TypeError：arrayName.sort不是函数

Question

• I am trying to sort the values using the map method.
• but I am getting an error Uncaught TypeError: arrayName.sort is not a function.
• can you tell me how to sort it.

• can you tell me how to solve using the below methods, since I am learning functional programmming

  .map() .filter() .find() .replace() .reduce() forEach()

• providing my code below.

// ARRAY 2
const newieyork = [
  {
    name: 'Michelle',
    age: 19,
    coder:true,
    gender: 'f',
    us: true,
  },
  {
    name: 'Sam',
    age: 25,
    coder:false,
    gender: 'm',
    us: false,
  },
  {
    name: 'Ivy',
    age: 26,
    coder:true,
    gender: 'f',
    us: false,
  },
  {
    name: 'Nick',
    age: 32,
    coder:true,
    gender: 'm',
    us: true,
  },
  {
    name: 'Jim Beglin',
    age: 65,
    coder:false,
    gender: 'm',
    us: true,
  },
]

// Part 1 - List all users in US in ascending order
newieyork.sort();
//console.log("newieyork.sort();--->", newieyork.sort());
newieyork.map(function(newieyork){
  //console.log("texasss.name--->", newieyork.name);
 let arrayName =[];
arrayName = newieyork.name;
console.log("arrayName--->", arrayName.sort()); 



});

Answer 1

In your code you are assigning to a string:

let arrayName =[];
arrayName = newieyork.name; // Assigning to a string

sort is not a method on a string.
