javascript - 删除部分对象js

Question

我有这样的字符串数组:

myarray = ["第一个单词","第二个单词","更多",]

我需要从数组中删除每个第二个单词。

结果:

myarray = ["first","second","smth",]

Answer 1

您可以使用 Array.prototype.map()

var yourArray = ["first word","second word","smth more"];

var yourNewArray = yourArray.map( item => { 
   return item.split(' ')[0];
});


console.log(yourNewArray);

或与 Array.prototype.forEach() 大致相同

var yourArray = ["first word","second word","smth more"];
var yourNewArray = [];

yourArray.forEach( item => {
    yourNewArray.push(item.split(' ')[0])
});

console.log(yourNewArray);
