Changelog

[2.0.0] - 2019-09-07

Added

• Better support for arrays, including literals: [ 1, 2, 3 ] and indexing: array[0]
• New functions for arrays: join, indexOf, map, filter, and fold
• Variable assignment: x = 4
• Custom function definitions: myfunction(x, y) = x * y
• Evaluate multiple expressions by separating them with ;
• New operators: log2 (base-2 logarithm), cbrt (cube root), expm1 (e^x - 1), log1p (log(1 + x)), sign (essentially x == 0 ? 0 : x / abs x)

Changed

• min and max functions accept either a parameter list or a single array argument
• in operator is enabled by default. It can be disabled by passing { operators: { 'in': false } } to the Parser constructor.
• || (concatenation operator) now supports strings and arrays

Removed

• Removed the if(condition, trueValue, falseValue) function. Use the ternary conditional operator instead: condition ? trueValue : falseValue, or you can add it back easily with a custom function.
