* Minimally working
* Added tests, toString
* Added tests for evaluation
* Minor changes
* Added a line in the docs about chained conditionals
* Documentation, replacing var and let with const
* chore(package): update standard to version 12.0.0
* update to new lint version with --fix
I believe this mainly adds whitespace to `{}`'s.
* Replace assert.equal with assert.strictEqual
This breaks a lot of tests which I will endevour to fix in the next
commits.
* Fix most errors due to assert.strictEquals
Some instances of `strictEquals` are replaced by `deepEquals`.
`toString` has been used to make some string comparisions explicit.
Tests will still fail untill #1236 and #1237 are fixed.
* Fix assertion erros due to -0
With node 10, assert.strictEqual no longer considers `0 === -0`.
I missed these first time round as I was using node 8.
* Put toString correct side of bracket
I was converting the constructor to a string rather
than the result of the computation. Oops.
* Fixed#1236: quantileSeq has inconsistant return
* Update package-lock
* Fixed#1237: norm sometimes returning a complex number instead of number
* Fix cli tests
* More changes for standardjs, and fixes in unit tests
`state.c` is always equal to `state.expression.charAt(state.index)`.
Therefore, the property `c` does not need to be included in the state.
This commit replaces all occurances of `state.c` with `currentCharacter(state)`.
This commit adds two functions:
- `currentCharacter` replaces `state.c`
- `currentString` which returns a substring starting at the current character.
Rename `nextPreview` and `prevPreview` to `nextCharacter` and `prevCharacter`
respectively so that these function names reflect the purpose of these functions.
This commit entirely removes the global state from `parse`.
The state is passed as an object to each function, functions modify the state passed to them.
Combines most of the global state used when passing expressions into an object called `state`.
This makes it easier to refactor this code going forward and clarifies which functions touch the global state.
`tokenStates` is still a seperate global variable which now contains copies of the state.
