This blog exhibits my understanding of functions as well as control flow, through the use of if/else statements. Below are 4 functions which all do different things:
Function 1 outputs an alert to the users browser when the function is run
Function 2 outputs to the console a persons first and last name which are taken as arguments in the function
Function 3 operates the same as 2, but uses a return statement instead to control the data type of the returned value
Function 4 uses an if/else if/else statement that changes what statement is outputted to the console depending on what number is passed through as an argument in the function

JavaScript Code

	//Function 1 
    function Sentence(){ 
        alert('Hello World');
    }
    //Calling function 1
    Sentence();
    //Function 2
    function FullName(first, last){
        console.log(`${first} ${last}`);
    }
    //Calling function 2
    FullName('Toby', 'Culverwell'); 
    //Function 3
    function FullName2(first2, last2){
        const fullName = first2 + ' ' + last2;
        return fullName;
    }
     //Calling function 3
    console.log(FullName2('Frank', 'Sinatra')); 
    //Function 4
    function TemperatureCheck(temperature){
        if (temperature < 0) {
            console.log('Stay Inside');
        }
        else if (temperature < 30) {
            console.log('Wear a coat and hat');
        }
        else if(temperature < 50){
            console.log('Wear a coat');
        }  
        else{ 
            console.log('Pants and vest are fine');
        }
    }
    //Calling function 4
    const num1 = 35;
    const num2 = 25;
    const num3 = -5;
    const num4 = 55;
    TemperatureCheck(num1);
    TemperatureCheck(num2);
    TemperatureCheck(num3);
    TemperatureCheck(num4);
