A literal math expression reducer made with web technologies (TypeScript + Sass)

Unexpected result when reducing: (x+y)(x+y)/(x+y)
https://martinheywang.github.io/literal-calculator-web/?expression=(x%2By)(x%2By)%2F(x%2By)
Input: (x+y)(x+y)/(x+y)
Current output: (x^2 + y^2 + 2xy)|(x + y)
Expected output: (x+y)
The result is not wrong in itself. The program develops (x+y)(x+y)
and then fails at dividing by (x+y)
.
*Error when reducing: '((2+1)3)^2'
Input: '((2+1)*3)^2'
Message: "Can't stringify term of an unknown type."
Error when reducing: 'h + (-1)'
https://martinheywang.github.io/literal-calculator-web/?expression=h%20*%20(-1)
Input: 'h + (-1)'
Message: "can't access property "data", expression.right.operator is undefined"
Error when reducing: '(h-1)^3'
Input: '(h-1)^3'
Message: "can't access property "symbol", operators[term.data.name] is undefined"
Looks weird...
Unexpected result when reducing: '536x - 45x^2'
https://martinheywang.github.io/literal-calculator-web/?expression=536x%20-%2045x%5E2
Input: '536x - 45x^2'
Current output: 491x^2
Expected output: -45x^2 + 536x
The algorithm should not sum up x and x squared together.
Unexpected result when reducing: '2|3 + 5|3'
https://martinheywang.github.io/literal-calculator-web/?expression=2%7C3%20%2B%205%7C3
Input: '2|3 + 5|3'
Current output: 2 | 3 + 5 | 3
Expected output: 7 | 3
The program should be able to sum up fractions together, it looks like it is not doing anything here.
Unexpected result when reducing: '2*(x+1)^2/6'
Input: '2*(x+1)^2/6'
Current output: (2x^2 + 4x + 2) | 6
Expected output: (x^2 + 2x + 1) | 3
The algorithm should be able to simplify fractions with an expression at the numerator or the denominator.
All literal expressions that equal zero fails at reducing.
The console shows a recursion error.
