Challenge Use Conditional Logic with If Statements
We can use if
statements in JavaScript to execute code only if the specified condition is met.
Each if
statement requires a boolean
condition to evaluate. If the boolean evaluates to true
, the statements inside the curly braces will execute. Otherwise, if it evaluates to false
, the code will not execute.
Example
function trueOrFalse(myVal) {
if (myVal > 10) {
return "Greater Than";
}
return "Not Greater Than";
}
If myVal
is greater than 10
, the function will return "Greater Than"
. If it is not, the function will return "Not Greater Than"
. Both return
statements will never get executed because as soon as the first one is encountered, the execution exits the function and returns control to where the function was called.
