What are they used for ?
Conditionals ? First of all, before we talk about what conditionals let's break it down to the word (condition).
What is a Condition ?
A condition is to have a significant influence on or determine (the manner or outcome of something).
What are Conditionals ?
Conditional control behavior in JavaScript and determine whether or not pieces of code can run. There are different types of conditionals in JavaScript including: “If” statements. Conditionals are expressions that evaluate to either true or false.
What are they used for ?
They tell you whether the code you put in is true or it is false.
Examples :
let number = 9;
if(number === 5){
console.log(5)
}
else{
console.log('number is not equal to 5')
}
basically this code says let the number equal to 9, then it says if the number is 5 ( they use 3 equal to, to show that you know and sure it is equal to this) console.log 5 (print 5) else print number is not equal to 5.
this is going to print
number is not equal to 5
Why are Conditionals important ?
Conditional statements help mathematicians and computer programmers make decisions based on the state of a situation.
