A brief³ literature review only finds one article studying the efficacy of library security systems [1]. Since Hamilton Library is doing us a favor in allowing us to hold class sessions in the basement, we will attempt to gather data⁴ on the utility value of the security gates in the library in repayment of that debt.

Create a function that:

Takes an array of objects as its sole parameter. Each object represents a single day of observation and will contain key-value pairs indicating the data gathered. For example, the data below would indicate one true positive, four false positives, eight true negatives, and two false negatives.

{ truePositives: 1, falsePositives: 4, trueNegatives: 8, falseNegatives: 2, } 

Returns an object containing the total amount of true positives, false positives, true negatives, and false negatives⁵ in the parameter array.

Examples

console.log(analyzeSecurity([ { truePositives: 1, falsePositives: 4, trueNegatives: 8, falseNegatives: 2, }, { truePositives: 2, falsePositives: 4, trueNegatives: 16, falseNegatives: 1, } ])); /* * Prints: * { * truePositives: 3, * falsePositives: 8, * trueNegatives: 24, * falseNegatives: 3 * } */
