Tutorial : simple if else statement (ternary operator) - MAKE IT EASY 📌

Question

Hello I wanted to share a trick.
https://code.sololearn.com/Wirdh4rMXimn/

if(foo === 0) {
foo+= 1 ; } else {
foo+= 2 ; }

=

foo===0 ? foo+=1 : foo+=2

condition ? execute when true : execute when false

You can also chain the statements (left propagation)

foo%100 ? foo%400 ? true : false : false

Can be readed like this : foo % 100 is not equal to zero => return false (the last one), foo % 100 is equal to zero => check next condition which is foo% 400 equal to zero.

Please check the code for more !
