js 数组的实例方法

自己用到的数组实例方法

• forEach

const array1 = ['a', 'b', 'c'];
array1.forEach(element => console.log(element));
// expected output: "a"
// expected output: "b"
// expected output: "c"`

• for...of

const array1 = ['a', 'b', 'c'];

for (const element of array1) {
  console.log(element);
}

• find

const array1 = [5, 12, 8, 130, 44];
const found = array1.find(element => element > 10);
console.log(found);
// expected output: 12`

• filter

const words = ['spray', 'limit', 'elite', 'exuberant', 'destruction', 'present'];
const result = words.filter(word => word.length > 6);
console.log(result);
// expected output: Array ["exuberant", "destruction", "present"]`
