Sure, here's an explanation of how to use the if statement in TypeScript:
The if statement is used for conditional execution of code based on a condition. The general syntax for an if statement in TypeScript is as follows:
if(condition) {
// code to execute if the condition is true
}
Here, condition is any expression that can be evaluated to true or false. If the condition is true, then the code within the block {} will be executed. If the condition is false, then the code within the block will be skipped, and the program will continue to the next statement.
Here's an example to illustrate the use of if statement in TypeScript:
let age: number = 17;
if(age >= 18) {
console.log("You can vote in the election!");
} else {
console.log("You can't vote in the election yet.");
}
In this example, we have defined a variable age and used an if statement to check whether the value of age is greater than or equal to 18. If the condition is true, then the first console.log statement is executed. Otherwise, the second console.log statement is executed.
I hope this helps! Let me know if you have any questions.
