Practical Application of Javascript Assignment Operators

Javascript assignment operators example in real-life coding

let number = 10;
number = number + 5;  // The variable number now holds the value 15

let number = 10;
number += 5;  // Use of '+=' compound assignment operator

How to use Javascript Assignment Operators effectively

• Utilise compound assignment operator to reduce redundancy. If you're doing an operation (like addition, subtraction, etc.) and want to assign the result back to original variable, compound assignment operator is an optimal choice.
• Remember that assignments evaluate right-to-left. So, in expressions like `a = b = c = 5;`, all variables will have the value 5.
• Use parentheses to clarify order of operations in complex expressions. This may not involve assignment operators directly, but can help ensure that values are correct before assignment.
• Use logical assignment operators introduced in ES2021 where applicable. They can make your code cleaner and more readable.

Mastering Javascript Assignment Operators

Tips and Tricks for Using Javascript Assignment Operators

let x = 10;

// Instead of x = x + 5;
x += 5;

let a, b, c;

// Assigns 5 to a, b, and c
a = b = c = 5;

let x = 5;

x++;  // x is now 6
x--;  // x is back to 5

Common mistakes to avoid with Javascript Assignment Operators

let x = 5;
if (x = 10) {   // This will always evaluate as true
    // This code will always run because x = 10 is an assignment, not a comparison
}

let x = 5;

console.log(x == '5'); // true
console.log(x === '5'); // false
