Short-circuit evaluation

let tool = ''; //since is empty string, it will take the default value of 'pen' as tool is falsy.


// Use short circuit evaluation to assign writingUtensil variable below:
let writingUtensil = tool || 'pen';

console.log(`The ${writingUtensil} is mightier than the sword.`);

/*
The variable writingUtensil will be assigned the actual value of tool if is truthy,
while it will be assigned the value of 'pen' if tool is falsy.
