1. Handling Truthy/Falsy Values: Beginners vs Pros

Beginners:

Noobs might use if (!variable) to handle falsy values, but it might not cover all edge cases.

Pros:

Pros leverage the logical nullish assignment operator (||=) for concise and safer handling of falsy values.

Beginners:

Novice developers might use explicit property assignment for object creation, which is verbose.

Pros:

Pros utilize property shorthand for object creation, improving readability and reducing redundancy.

3. Dealing with Null or Undefined: Beginners vs Pros

Beginners:

Noobs might use explicit checks for null or undefined values.

Pros:

Pros leverage the nullish coalescing operator (??) for concise null or undefined checks and default value assignments.

4. Ensuring Unique Elements in Arrays: Beginners vs Pros

Beginners:

Beginners might use a combination of Set and Array.from to ensure unique elements.

Pros:

Pros use the spread operator directly with Set for a more concise and elegant way to get unique array elements.

5. Simplifying Exponentiation: Beginners vs Pros

Beginners:

Noobs might use Math.pow() for exponentiation.

Pros:

Pros use the exponentiation operator (**) for clearer and more concise exponentiation syntax.

6. Handling Floating-Point Math: Beginners vs Pros

Beginners:

Beginners might use toFixed() for precise floating-point arithmetic.

Pros:

Pros use Number() to convert the fixed number back to a numerical value for more accuracy.

7. Simplified Object Assignments: Beginners vs Pros

Beginners:

Noobs might manually assign default properties.

Pros:

Pros use the spread operator to merge objects and apply additional properties concisely.

8. Enhanced Error Handling: Beginners vs Pros

Beginners:

Noobs might only log the error message in the catch block.

Pros:

Pros might log the entire error object for better debugging and detailed error information.

9.Managing Strings: Beginners vs Pros

Beginners:

Novices might concatenate strings using +.

Pros:

Pros use template literals for string interpolation due to their readability and ease of use.

10. Using Short-Circuit Evaluation: Beginners vs Pros
