Lodash 有许多易于使用的方法,有助于处理集合。本章详细讨论它们。
Lodash 提供了各种方法来处理集合,如下所示 -
| 先生。 | 方法和语法 | 
|---|---|
| 1 | _.countBy(集合, [iteratee=_.identity]) | 
| 2 | _.every(集合, [谓词=_.identity]) | 
| 3 | _.filter(集合, [谓词=_.identity]) | 
| 4 | _.find(集合, [谓词=_.identity], [fromIndex=0]) | 
| 5 | _.findLast(集合, [谓词=_.identity], [fromIndex=collection.length-1]) | 
| 6 | _.flatMap(集合, [iteratee=_.identity]) | 
| 7 | _.flatMapDeep(集合, [iteratee=_.identity]) | 
| 8 | _.flatMapDepth(集合, [iteratee=_.identity], [深度=1]) | 
| 9 | _.forEach(集合, [iteratee=_.identity]) | 
| 10 | _.forEachRight(集合, [iteratee=_.identity]) | 
| 11 | _.groupBy(集合, [iteratee=_.identity]) | 
| 12 | _.includes(集合, 值, [fromIndex=0]) | 
| 13 | _.invokeMap(集合、路径、[args]) | 
| 14 | _.keyBy(集合, [iteratee=_.identity]) | 
| 15 | _.map(集合, [iteratee=_.identity]) | 
| 16 | _.orderBy(集合, [iteratees=[_.identity]], [订单]) | 
| 17 号 | _.partition(集合, [谓词=_.identity]) | 
| 18 | _.reduce(集合, [iteratee=_.identity], [累加器]) | 
| 19 | _.reduceRight(集合, [iteratee=_.identity], [累加器]) | 
| 20 | _.reject(集合, [谓词=_.identity]) | 
| 21 | _。样品采集) |
