An if
statement in JavaScript is used for conditional execution. It evaluates a condition inside parentheses and executes a block of code if the condition is true.
Example: Here, the if
statement checks whether the variable num
is greater than 0
. If the condition num > 0
evaluates to true
, the code block inside the curly braces (console.log("Number is positive.")
) is executed, and it prints “Number is positive.” to the console.
Javascript
let num = 10; if (num > 0) {
console.log( "Number is positive." );
} |
Output
Number is positive.
