var rate_ = amount/quantity;
var newRate = context.newRecord.setValue({

value : ('rate',rate_)

Your code is not syntactically valid. Please replace below code
var newRate = context.newRecord.setValue({
fieldId: 'rate'
value: ('rate', rate_)
});
with
var newRate = context.newRecord.setValue({
fieldId: 'rate',
value: ('rate', rate_)
});
You can try validating your code with JS syntax validator esprima. Although alot of IDE's now support validation.
