the difference between 'null' and 'false' ?

[nozer0]

If I convert these terms from 'jack' to 'vm', do they get the same result?

'let a = null'
-> 'push constant 0' 'pop local 0'

'let a = false'
-> 'push constant 0' 'pop local 0'

'let a = 0'
-> 'push constant 0' 'pop local 0'

The Jack specification says that "null and false are mapped to the constant 0."

There should be no difference in the generated VM code whether you use null, false or 0.
