String Array Group By at Jesse Oliver blog

String Array Group By. First, separate grouping and aggregating. we can use the new groupby function by calling it on the array instance, just like using a map, filter, or reduce. Lets declare prototypical group by function. Previously, developers had to build their own. because grouping data is an often occurring task (recall group by from sql?) the array group proposal introduces two useful methods: grouping data is common but currently unavailable in the standard javascript array api. Constructor(key:string) { this.key = key; Groupby (( item , index , array ) => { //. array.groupby returns an object where each property has the key as the value returned by the arrow function and value as an array of objects matching the criteria. i'd like to suggest my approach. two such apis for grouping of array data are `array.prototype.group and array.prototype.grouptomap. class group { key:string; Here's how to use object.groupby() to create the same grouping by category:
