Math.js supports chaining operations by wrapping a value into a Chain. A chain can be created with the function math.chain(value) (formerly All functions available in the math namespace can be executed via the chain. The functions will be executed with the chain’s value as the first argument, followed by extra arguments provided by the function call itself.

    .done(); // 5

math.chain( [[1, 2], [3, 4]] )
    .subset(math.index(0, 0), 8)
    .done(); // [[24, 6], [9, 12]]


A Chain is constructed as:


The Chain has all functions available in the math namespace, and has a number of special functions:
