lodash

问题 I have a bothersome length of characters before all keys in this object. Since they are all the same, I would like to do a .map() or forEach() or something with a .slice() in it to remove the first n characters. How is this done to all keys in the object? I should say that we are already importing Lodash in the project so I can use that. So I need to turn this: { 'remove.this.string.a': "apple", 'remove.this.string.b': "banana", 'remove.this.string.c': "carrot", 'remove.this.string.d':

问题 I have an array of components: let components = ["a", "b", "c"]; It is possible to combine those components to make products; i.e., "a" + "b" = "ab" . I have a catalog of possible products: let catalog = ["ab", "ac", "bc"]; Using something like lodash, we can create an array of possible products. Output array would look like ["ab", "ac", "bc"] . But the problem is that not all of those products could be built because once the component for one is used, it is no longer available for use in

问题 I need a function isSubset, which when given two objects compares its values and tell if one object is subset of another. object1 = { pickUpLocation : {city : 'Hyderabad', state: 'Telangana' }}; object2 = { dist : 322, pickUpLocation: {city : 'Hyderabad', state: 'Telangana' }}; isSubset(object1, object2); //should return true object3 = { pickUpLocation : {city : 'Chennai', state: 'Telangana' }} object4 = { dist : 322, pickUpLocation: {city : 'Hyderabad', state: 'Telangana' }} isSubset(object3
