what's the difference between "ternary"operator and ifelse statement?

Question

sample1:Ternary operator
var myNum1 = 7;
var myNum2 = 10;
if (myNum1 < myNum2) {
alert("JavaScript is easy to learn.");
}

sample2:Ifelse statement
var myNum1 = 7;
var myNum2 = 10;
(myNum1 < myNum2 ) ? alert("javascript is easy to learn") : "" ;

Answer 1

Readability - Use If else or Switch case
Reliability - Use ternary operators
Speed - Use ternary operators

Ternary operators are the shortest path to write a program like comparing 3 numbers , and output the greatest number from them , Eg . A program for this case using if else is more than 8 lines but ternary takes it only 1 line in this way :-

a>b?b>c?'a':c>b:'c':'a';

Just that much .. Hope you understand .

Answer 2

its better to use if else because readability
use ternary if ur defining functions that u wont see it again for example like lets say u wanna have a function that validates sth, u can do sth like
lol=s=>/\d/.test(s)?true:false
ok so lol() is a function to validate whether a string contains a number and using ternary is fine

Answer 3

ternary is shorter

Answer 4

ternary is like a shortcut

Answer 5

Saves ur time

Answer 6

beside the way you write it down :)
is there a bestway practice. when to you use ifelse and when the ternary operator?

Answer 7

ternary operator needs to have all it's paths return the same type. if else statement does not have this requirement. but following it as a matter of discipline makes for easier maintenance. you don't want to be spewing expletives at the you from 6 weeks or 6 months ago.

however, if you are not returning any value, instead, say doing something like if under 21, add to table x, if 21 or over, add to table o, if else is better. this type of operation that does not return anything and affects the state of the world is called impure operation.

this shouldn't have been the case. Kotlin has just if else expressions. No ternary operator, no if else statement.
