What is the best way to streamline the following code:
rules = rules.map(rule => Object.assign(rule, rule.ruleOption.options))
rules.forEach(rule => delete rule.ruleOption)
rules = _.keyBy(rules, 'code')
I have recently started using Lodash and am trying to properly understand how to use it effectively.
If you want to extract specific values using destructuring in JavaScript while also utilizing the rest syntax, you can achieve this by extracting ruleOption and then merging it into a new object. To combine ruleOptions.options with the remaining properties of the object, you can make use of object spread:
const rules = [{ code: 'x', ruleOption: { options: { type: 'a' }}}, { code: 'y', ruleOption: { options: { type: 'b' }}}];
const newRules = _.keyBy(
rules.map(({ ruleOption, ...obj }) => ({ ...obj, ...ruleOption.options })),
'code'
)
