I've been struggling with this exercise.
addCharacter: function (name, lastName, house, dateOfBirth, isMuggle)
{
let id = 0;
for (let i = 0; i < houses.length; i++) {
if (house === houses[i]) {
id = i + 1;
}
}
if (id === 0) {
return null;
}
const date = dateOfBirth.split("-").reverse().join("-");
const d = new Date(date);
const year = d.getFullYear();
const character = {
name,
lastName,
houseId: id,
dateOfBirth,
yearOfBirth: year,
isMuggle,
wand: {},
spells: [],
};
characters.push(character);
return character;
}
I need to add properties to wand object with this format {wood: wood, core: core, length: length}
addWand: function (name, wood, core, length) {
const character = characters.find((character) => character.name === name);
if (!character) return [];
if (character.wand !== undefined) {
return null
}
}
Been trying with dot notation, assign method and spread operator but I can't make it work. Thanks in advance.
Is this what you're looking for?
addWand: function (name, wood, core, length) {
const character = characters.find((character) => character.name === name);
if (!character) return [];
if (character.wand == undefined) {
// 'wand' property doesn't exist, so create it from wood, core, and length:
character.wand = { wood, core, length }
} else {
// 'wand' property exists, so *add* wood, core and length:
character.wand = { ...character.wand, wood, core,length }
}
}
If characters are always created with a wand property (as seems to happen with your addCharacter function), there is no need to check for if (character.wand == undefined) {. In this case the addWand code can be simplified to:
addWand: function (name, wood, core, length) {
const character = characters.find((character) => character.name === name);
if (!character) return [];
// 'wand' property exists, so *add* wood, core and length:
character.wand = { ...character.wand, wood, core,length }
}
Normal Assignment should be working. Find the snippet below:
let characters = [];
let houses = ["big", "small", "medium"];
let addCharacter = (name, lastName, house, dateOfBirth, isMuggle) => {
let id = 0;
for (let i = 0; i < houses.length; i++) {
if (house === houses[i]) {
id = i + 1;
}
}
if (id === 0) {
return null;
}
const date = dateOfBirth.split("-").reverse().join("-");
const d = new Date(date);
const year = d.getFullYear();
const character = {
name,
lastName,
houseId: id,
dateOfBirth,
yearOfBirth: year,
isMuggle,
wand: {},
spells: [],
};
characters.push(character);
return character;
}
let addWand = function(name, wood, core, length) {
const character = characters.find((character) => character.name === name);
if (!character) return [];
if (character.wand === undefined) {
return null
} else {
character.wand = {
"wood": wood,
"core": core,
"length": length
};
}
}
addCharacter("john", "doe", "big", "18/9/1994", true);
addWand("john", "123", "12", "12");
addCharacter("misty", "doe", "big", "18/9/1994", true);
addWand("misty", "1234", "123", "123");
console.log(characters);
