JavaScript, the concept of "left-to-right" often called left-to-right evaluation or left-to-right associativity

Javascript 
let result = 5 + 3 * 2;
console.log(result); // Output: 11

Here’s the breakdown:

• The * (multiplication) operator has higher precedence than + (addition), so JavaScript will evaluate 3 * 2 first, resulting in 6.
• Then, it evaluates 5 + 6, which results in 11.

Even though the expression goes left-to-right for addition and multiplication, operator precedence affects the order in which operations occur.

Example 2: Assignment with Multiple Operations

javascript 
let x = 2;
let y = 3;
let result = x + y * 4 - 1;
console.log(result); // Output: 13

1. First, y * 4 is evaluated (left-to-right) because multiplication has higher precedence than addition and subtraction, giving 12.
2. Then, x + 12 is calculated (left-to-right), which is 2 + 12 = 14.
3. Finally, 14 - 1 is calculated, resulting in 13.

Example 3: Logical Operators

JavaScript also evaluates logical operators left to right:

javascript 
let a = true;
let b = false;
let result = a && b || true;
console.log(result); // Output: true

• First, a && b is evaluated (left-to-right), which results in false because b is false.
• Then, false || true is evaluated, which results in true.

Example 4: Chaining Assignments

javascript
let x = 5;
let y = x = 10;
console.log(x); // Output: 10
console.log(y); // Output: 10

Here, the assignment is evaluated left-to-right:

1. x = 10 is executed first, so x becomes 10.
2. Then, y = 10 is executed, so y also gets the value 10.
