Returns: Iterator · Updated March 13, 2026 · Map and Set

map values iteration

The values() method returns a new Iterator object containing all the values in the Map. The values are returned in the same order they were inserted into the Map.

Syntax

map.values()

Parameters

None.

Return Value

A new Iterator object containing the values of the Map.

Examples

Getting all values as an array

const userRoles = new Map([
  ['alice', 'admin'],
  ['bob', 'editor'],
  ['charlie', 'viewer']
]);

console.log([...userRoles.values()]);
// ['admin', 'editor', 'viewer']

Iterating with for…of

const prices = new Map([
  ['apple', 1.5],
  ['banana', 0.75],
  ['orange', 2.0]
]);

for (const value of prices.values()) {
  console.log(`$${value}`);
}
// $1.5
// $0.75
// $2.0

Calculate total from values

const inventory = new Map([
  ['apples', 50],
  ['bananas', 30],
  ['oranges', 25]
]);

const total = [...inventory.values()].reduce((a, b) => a + b, 0);
console.log(total); // 105

Find specific value

const products = new Map([
  ['sku1', { name: 'Widget', stock: 10 }],
  ['sku2', { name: 'Gadget', stock: 0 }]
]);

const outOfStock = [...products.values()].find(p => p.stock === 0);
console.log(outOfStock); // { name: 'Gadget', stock: 0 }

Values with forEach

const scores = new Map([
  ['alice', 95],
  ['bob', 82],
  ['charlie', 91]
]);

scores.forEach((value) => {
  console.log(`Score: ${value}`);
});

Transform values to array

const data = new Map([
  ['a', '  hello  '],
  ['b', '  world  ']
]);

const trimmed = [...data.values()].map(s => s.trim());
console.log(trimmed); // ['hello', 'world']

Common Patterns

Get unique values as Set

const roles = new Map([
  ['alice', 'admin'],
  ['bob', 'editor'],
  ['charlie', 'admin'],
  ['dave', 'viewer']
]);

const uniqueRoles = new Set([...roles.values()]);
console.log([...uniqueRoles]); // ['admin', 'editor', 'viewer']

Check if all values pass a test

const temperatures = new Map([
  ['morning', 72],
  ['afternoon', 85],
  ['evening', 78]
]);

const allWarm = [...temperatures.values()].every(t => t > 60);
console.log(allWarm); // true
