- Write a block of code that checks and logs whether variables are equal or not.
let num = 3
let bar = 10
if ( num === bar){
console.log('Yes')
}else
{
console.log('No')
}
- Write a block of code that logs which of two number variables is larger.
- Your output should look like this (in this example for the numbers x = 5 and y = 10): 'The greater number of 5 and 10 is 10'
- If the two numbers are equal, log: 'The numbers are equal.'
let num = 10
let bar = 1
if (num > bar){
console.log('The greater number of ' + num + ' and ' + bar + ' is ' + num )
} else if (num < bar){
console.log('The greater number of ' + num + ' and ' + bar + ' is ' + bar )
} else {
console.log('They are equal')
}
- Create a string variable with a language code (e.g. "english", "spanish", "german"). Use an if - else if - else statement to log "Hello, World" in the given language, for at least 3 languages. It should default to logging English.
let language = 'English'
if (language === 'German'){
console.log('Hallo Welt')
} else if (language === 'Spanish'){
console.log('Hola Mundo')
} else if (language === 'English'){
console.log('Hello World')
} else {
console.log('Done checking')
}
- Do question 3 again but this time use a
switchstatement.
switch (language = 'English'){
case 'German':
console.log('Hallo Welt')
break;
case 'Spanish':
console.log('Hola Mundo')
break;
case 'English':
console.log('Hello World')
break;
default:
console.log('Done checking')
}
- Create a variable numGrade that will contain a numeric grade (out of 100). Use an if - else if ... - else statement to log the corresponding letter grade, either "A", "B", "C", "D", or "F".
let grade = 100
if (grade > 90) {
console.log('A')
} else if (grade > 80 ) {
console.log('B')
} else if (grade > 70){
console.log('C')
} else if (grade > 60){
console.log('D')
} else {
console.log('F')
}
- Create two variables: animalName ('cat', 'dog', etc.) , and numberOfAnimals.
Use an if - else statement to log:
-
the number
-
either in single or plural form. Exp: "5 cats" or "1 dog".
Bonus: Make it handle a few collective nouns like "sheep" and "geese".
let typeOfAnimal = ' cat'
let numberOfAnimals =12
if (numberOfAnimals === 1){
console.log(numberOfAnimals + typeOfAnimal)
} else {
console.log(numberOfAnimals + typeOfAnimal + 's')
}
- Write a block of code that logs whether a given number is even or odd.
let weather = 99
if (weather % 2 === 0) {
console.log('Even')
} else {
console.log('Odd')
}
- Do question 7 again but use a ternary.
let weather =100
weather % 2 === 0 ? console.log('Even'): console.log('Odd')
- Write a block of code that checks and logs whether a given number is positive, negative, or equal to 0.
let num = 10
if (num > 0){
console.log('Positive')
} else if (num < 0){
console.log('Negative')
} else {
console.log("Equal")
