How is division before multiplication in Javascript?

I run some code and I get same results with or without parenthesis, even if I know that multiplication have higher precedence then division. Here is example:

let calculate = 16 / 30 * 100

I gott same result as 

let calculate = (16 / 30) * 100

So I don't know which of them has higher precedence.

See this fiddle: https://www.w3schools.com/code/tryit.asp?filename=FRB0CCQOKZT2

the code is evaluated in this order:

  • Parentheses
  • Multiply and Divide
  • Addition and Subtraction

If you have Multiple and Divide in the same equation then it evaluates the first one it encounters. you can override this by using parentheses.

Neither, they have the same precedence and associativity; see MDN's page for details.

Almost all programming languages adhere to PEMDAS:

  • PE - Parentheses and Exponents
  • MD - Multiplication and Division
  • AS - Addition and Subtraction

...aka BODMAS:

  • BO - Brackets and Orders
  • DM - Division and Multiplication
  • AS - Addition and Subtraction
