What is if and else in JavaScript?
Use if to specify a block of code to be executed, if a specified condition is true. Use else to specify a block of code to be executed, if the same condition is false. Use else if to specify a new condition to test, if the first condition is false.
Can you have 3 conditions in an if statement JavaScript?
We can also write multiple conditions inside a single if statement with the help of the logical operators && and | | . The && operators will evaluate if one condition AND another is true. Both must be true before the code in the code block will execute.
What is the example of if else?
Example 2: if...else statement
Enter an integer: 7 7 is an odd integer. When the user enters 7, the test expression number%2==0 is evaluated to false. Hence, the statement inside the body of else is executed.
What can I use instead of if else in JavaScript?
Javascript offers a ternary operator which acts like a one-line if / else statement with a single condition. It works really well for conditionally assigning a value to a variable.
