What are some examples of operator precedence in JavaScript?

Can you explain operator precedence in JavaScript with some examples?

Sure! Operator precedence determines the order in which operators are evaluated in an expression. For example, in the expression 3 + 4 * 5, the multiplication is performed first, resulting in 3 + 20, which equals 23.

What about parentheses? Do they change the precedence?

Yes, parentheses can change the precedence. For instance, in the expression (3 + 4) * 5, the addition is performed first due to the parentheses, resulting in 7 * 5, which equals 35.

Can you give me another example with different operators?

Of course! Consider the expression 10 - 2 + 3 * 4. Here, multiplication has higher precedence, so it's evaluated first: 10 - 2 + 12, which simplifies to 8 + 12, resulting in 20.

What happens if I use the same operators, like + and -?

When using the same precedence level, like + and -, JavaScript evaluates from left to right. For example, in 10 - 5 + 2, it evaluates as (10 - 5) + 2, resulting in 5 + 2, which equals 7.
