Understanding the assignment and control flow mechanisms in JAVASCRIPT code

Can you explain how the following code snippet functions? It is a part of a JavaScript file.


this.isTabSelected = function(tabToCheck) {
  return (this.tab === tabToCheck);
}

Answer №1

this.isSelected is a custom function that accepts checkTab as an argument and compares it to this.tab. If they are equal, the function returns true; otherwise, it returns false.

this.isSelected = function(checkTab)
{
    return (this.tab === checkTab);
}

// Another way of writing the function
function isSelected(checkTab) {
    if(this.tab === checkTab) return true;

    return false;
}
