Conditional statements

Conditional statements determine whether to hold or skip a specified block of code by judging the results obtained

JAVASCRIPT provides two conditional statements: if else switch case

If statement

Code implementation

var num = 5; if (num <) {console.log (num);}

If Else statement

var score = 68; if (Score <) {Console.log ("failed")} else {Console.log ("Pass")}

If Else statement nesting

var score = 68; if (Score >) {console.log ("excellent")} else {if (score >=) {Console.log ("good")}else{Console.log ("? like")}}

else if statement

The else if statement is actually a nested notation for a simplified if else statement.

Switch Case statement

var num = 2; Switch (num) {case 1:console.log ("Enquiry Balance"), break, Case 2:console.log ("online recharge"), Break, Default:console.log ("go?? Service ")}
