Function scope refers to the scope of variables defined within a function. You can only access variable values within the scope and not outside. It helps to avoid having the same variable names and keeps your JavaScript code clean.

javascript
function myStudyPlan() { 
  var studyPlanOne = "Top JavaScript interview questions for web developers";
  let studyPlanTwo = "Top JavaScript interview questions for web developers";
  const studyPlanThree = "Top JavaScript interview questions for web developers"; 

  console.log(studyPlanOne); 
  console.log(studyPlanTwo);  
  console.log(studyPlanThree); 
} 

myStudyPlan(); // Calls the function
