How do I calculate the number of the key of a specific property from a JSON object

-1

Image I have a

const events: {

        '12327ae260fe9431': {

          eventType: 'DEVICE_LINK_ERR',

          key: '12327ae260fe9431',

          severity: 'ERROR',

          timestamp: 1542199782975,

          title: 'Link went down unexpectedly',

        },

        '62d29fab77bddd7': {

          eventType: 'DEVICE_LINK_ERR',

          key: '62d29fab77bddd7',

          severity: 'ERROR',

          timestamp: 1542199783055,

          title: 'Link went down unexpectedly',

        },

      },

I want to calculate the total severity and construct a severityCounts object like this

 severityCounts: {

        CRITICAL: 0,

        ERROR: 2,

        INFO: 0,

        WARNING: 0,

      }

and I have access to Lodash. How should I go about doing this?

Start small...first figure out how to iterate through the object and access each severity. Once you get there it's fairly easy to add 1 to a counter for that type

You could group the data by severity, get the length and assign all information to a single object.

var data = { '12327ae260fe9431': { eventType: 'DEVICE_LINK_ERR', key: '12327ae260fe9431', severity: 'ERROR', timestamp: 1542199782975, title: 'Link went down unexpectedly' }, '62d29fab77bddd7': { eventType: 'DEVICE_LINK_ERR', key: '62d29fab77bddd7', severity: 'ERROR', timestamp: 1542199783055, title: 'Link went down unexpectedly' } },

    result = _.assign(

        { CRITICAL: 0, ERROR: 0, INFO: 0, WARNING: 0 },

        ..._(data)

            .values()

            .groupBy('severity')

            .map(({ length }, key) => ({ [key]: length }))

            .value()

    );



console.log(result);

You can use Object.values() to generate an array of all your values and then using array#reduce you can create an object with a count of each severity count.

const events = { '12327ae260fe9431': { eventType: 'DEVICE_LINK_ERR', key: '12327ae260fe9431', severity: 'ERROR', timestamp: 1542199782975, title: 'Link went down unexpectedly', }, '62d29fab77bddd7': { eventType: 'DEVICE_LINK_ERR', key: '62d29fab77bddd7',severity: 'ERROR', timestamp: 1542199783055, title: 'Link went down unexpectedly', }, },

      severityCounts = Object.values(events).reduce((r, {severity}) => {

        r[severity] = ( r[severity] || 0 ) + 1;

        return r;

      },{ CRITICAL: 0, ERROR: 0, INFO: 0, WARNING: 0});

console.log(severityCounts);

Please always post your attempt in OP before asking so that we get to know where you are stuck

You can loop through the object using for .. of and increment counter like below. No need for lodash

const events = {

        '12327ae260fe9431': {

          eventType: 'DEVICE_LINK_ERR',

          key: '12327ae260fe9431',

          severity: 'ERROR',

          timestamp: 1542199782975,

          title: 'Link went down unexpectedly',

        },

        '62d29fab77bddd7': {

          eventType: 'DEVICE_LINK_ERR',

          key: '62d29fab77bddd7',

          severity: 'ERROR',

          timestamp: 1542199783055,

          title: 'Link went down unexpectedly',

        },

        '62d29fab77bddd71': {

          eventType: 'DEVICE_LINK_ERR',

          key: '62d29fab77bddd7',

          severity: 'INFO',

          timestamp: 1542199783055,

          title: 'Link went down unexpectedly',

        }

      }



let severityCounts = { CRITICAL: 0, ERROR: 0, INFO: 0, WARNING: 0 }



for(let { severity } of Object.values(events)) {

  severityCounts[severity] = severityCounts[severity] || 0

  severityCounts[severity]++

}



console.log(severityCounts)

You can use Object.values() to generate an array of all your values and then using array#reduce you can create an object with a count of each severity count.

      severityCounts = Object.values(events).reduce((r, {severity}) => {

        r[severity] = ( r[severity] || 0 ) + 1;

        return r;

      },{ CRITICAL: 0, ERROR: 0, INFO: 0, WARNING: 0});

You can use Object.values() to generate an array of all your values and then using array#reduce you can create an object with a count of each severity count.

const events = { '12327ae260fe9431': { eventType: 'DEVICE_LINK_ERR', key: '12327ae260fe9431', severity: 'ERROR', timestamp: 1542199782975, title: 'Link went down unexpectedly', }, '62d29fab77bddd7': { eventType: 'DEVICE_LINK_ERR', key: '62d29fab77bddd7',severity: 'ERROR', timestamp: 1542199783055, title: 'Link went down unexpectedly', }, },

      severityCounts = Object.values(events).reduce((r, {severity}) => {

        r[severity] = ( r[severity] || 0 ) + 1;

        return r;

      },{ CRITICAL: 0, ERROR: 0, INFO: 0, WARNING: 0});

console.log(severityCounts);

Please always post your attempt in OP before asking so that we get to know where you are stuck

You can loop through the object using for .. of and increment counter like below. No need for lodash

const events = {

        '12327ae260fe9431': {

          eventType: 'DEVICE_LINK_ERR',

          key: '12327ae260fe9431',

          severity: 'ERROR',

          timestamp: 1542199782975,

          title: 'Link went down unexpectedly',

        },

        '62d29fab77bddd7': {

          eventType: 'DEVICE_LINK_ERR',

          key: '62d29fab77bddd7',

          severity: 'ERROR',

          timestamp: 1542199783055,

          title: 'Link went down unexpectedly',

        },

        '62d29fab77bddd71': {

          eventType: 'DEVICE_LINK_ERR',

          key: '62d29fab77bddd7',

          severity: 'INFO',

          timestamp: 1542199783055,

          title: 'Link went down unexpectedly',

        }

      }



let severityCounts = { CRITICAL: 0, ERROR: 0, INFO: 0, WARNING: 0 }



for(let { severity } of Object.values(events)) {

  severityCounts[severity] = severityCounts[severity] || 0

  severityCounts[severity]++

}



console.log(severityCounts)
