列出数组中的重复值

Question

我有一个包含重复值的数组，如何列出这些值var result = [ { name: 'Maura Hickman' },  { name: 'Elena Vega' },  { name: 'Sylvia Norman' },  { name: 'Jana Stevenson' },  { name: 'Colon Reynolds' },  { name: 'Luisa Rutledge' },  { name: 'Pearson Marquez' },  { name: 'Sylvia Norman' },  { name: 'Jana Stevenson' },  { name: 'Colon Reynolds' } ]我试过这样做var obj = [ { name: 'Maura Hickman' },  { name: 'Elena Vega' },  { name: 'Sylvia Norman' },  { name: 'Jana Stevenson' },  { name: 'Colon Reynolds' },  { name: 'Luisa Rutledge' },  { name: 'Pearson Marquez' },  { name: 'Sylvia Norman' },  { name: 'Jana Stevenson' },  { name: 'Colon Reynolds' } ];if (Object.values(obj).indexOf('Jana Stevenson') > -1) {   console.log('has Jana Stevenson');}但它没有用。我期待的是以下内容var exist =  [{ name: 'Jana Stevenson'} , {name: 'Sylvia Norman' },{ name: 'Colon Reynolds'}]
