Depending upon this value, If statement executes a particular block of code. In the case of the if statement, the condition statement is mostly a Boolean variable or an expression returning Boolean variable it is either True or either False.

If Statement works in this way, if a condition is true, it will execute code from if block otherwise, if a condition is false, it will execute code from else block.

These are the statements that are used to decide the flow of execution depending on different conditions. JavaScript supports conditional statements like if statement, if… else… statement, switch case statement, etc.

This refers to dynamically choosing and executing the preferred part of the code. While writing programs, there might be a situation where we need to execute a particular part of it depending upon the situation. Decision-making statements are the backbone of any programming language because, depending upon the different scenarios and situations, we can execute particular statements. Like any other programming language, JavaScript has the ability to make decisions using conditional statements, which are very useful and required for decision making at runtime.
Then you can add some content changes to show the score. call it in the end game section instead of init.
