1. The primary purpose of an if statement in a TypeScript function is to execute a block of code conditionally based on a boolean expression.
2. The correct syntax for a simple if statement in a function is if (condition) { ... }.
3. The purpose of an else statement used with an if statement is to provide an alternative code block if the if condition is false.
4. If the condition in an if statement is false, the code block following the if statement (if any) is executed.
5. To check if a number is positive, negative, or zero, you can utilize an if…else if…else structure with conditions for each range.
6. The role of an else if statement in a chain of conditional statements is to provide an alternative code block if all previous if conditions were false.
7. The order of evaluation for an if…else if…else chain in a function is that the conditions are evaluated from top to bottom, stopping at the first true condition.
8. A common mistake when using if…else if…else statements is forgetting curly braces { } for code blocks within each statement.
9. The appropriate way to check if a variable is null or undefined in an if statement is if (variable === null || variable === undefined) { ... }.
10. To write a function that takes a grade as a number and returns a letter grade based on ranges, you can utilize an if…else if…else structure with conditions for each grade range.
