Sum two specific array numbers

// String Array

let strArray = [activitiesOfDailyLiving, socialRecreational, travel, interpersonalRelationships, concentrationPersistencePace,resilienceEmployability];

// convert strings to numbers in a separate array

let numArray = strArray.map(n => Number(n));

  • “=>” Arrow functions allow us to write shorter function syntax.
  • “Number(n)” Number(value) converts a string or other value to the Number type.
  • “strArray.map” The map() method creates a new array populated with the results of calling a provided function on every element in the calling array.

From what I understand, the following happens:

  1. Take a string strArray and map it thereby applying a functioning to each value in the string array.

  2. “n” is the name of a new function, which converts each passed on value to a number. The value is fed from step 1 strArray.map.
