Question

我如何使用lodash，用最少的代码转换像这样的数组：

['Alfa','Betta','Gamma','Delta']

成：

[
 { squad: 'Alfa'},
 { squad: 'Betta'},
 { squad: 'Gamma'},
 { squad: 'Delta'},
]

Answer 1

在Lo-Dash（或Underscore）中：

_.map(['Alpha', 'Beta', 'Gamma', 'Delta'], function (squad) {
    return { squad: squad };
});

在ES5中：

['Alpha', 'Beta', 'Gamma', 'Delta'].map(function (squad) {
    return { squad: squad };
});

在ES2015中：

['Alpha', 'Beta', 'Gamma', 'Delta'].map(squad => ({ squad }));

Answer 2

<script>
    var arrayOfSquads=['Alfa','Betta','Gamma','Delta'];
    var arrayOfThingsThatHaveSquads=new Array();
    for(i=0;i<arrayOfSquads.length;i++)
    {
        arrayOfThingsThatHaveSquads.push({"squad":arrayOfSquads[i]});
    }
    console.log("What's lodash?");
</script>
