Switch.js

/* 
Create a function called "timeAdder" that can add two time values together. For example, it should be able to add 25 hours and 3 days together. 
The function should accept 4 parameters:
value1, label1, value2, label2
- value1 and value2 should accept positive integers  
- label1 and label2 should accept any of the following strings: "seconds", "minutes", "hours", "days", "second", "minute", "hour", "day"
For example your function may be called in any of the following ways:
timeAdder(1,"minute",3,"minutes")
timeAdder(5,"days",25,"hours")
timeAdder(1,"minute",240,"seconds")

Requirements:
1. Your function should include at least one switch
2. Your function must accept any possible combination of inputs 
3. If the inputs are valid, it should return an array with 2 variables inside of it: value3, and  label3. For example:
return [5,"minutes"]; 
The exact label you choose to return for label3 ("minutes" for example) is up to you.
4. If the inputs are invalid or impossible, it should return false. Here are examples of impossible and invalid inputs:
timeAdder(5,"hour",5,"minutes") // This is impossible because "hour" is singular and 5 is plural
timeAdder(false,false,5,"minutes") // This is invalid because the first 2 arguments are not the correct types
timeAdder({},"days",5,"minutes") // This is invalid because the first argument is the wrong type
*/

    let firstLabel;
    let firstValue;
    let secondLabel;
    let secondValue;
    let fistValueSeconds;
    let secondValueSeconds;
    let totalSeconds;
    let finalResult;

    if(typeof value1 !== 'number'){console.log('This first argument is not a Number')}
    else if(typeof value2 !== 'number'){console.log('This fourth argument is not a Number')}
    else if(typeof label1 !== 'string'){console.log('The second argument is not a String')}
    else if(typeof label2 !== 'string'){console.log('The thirdargument is not a String')}

        secondValueSeconds = secondsConvert(secondLabel, secondValue);
