#### Build and compile a contract

``js
const { Equal, Contract, EntryPoint,GetSender, NewVariable, Require, SetValue, TNat, ContractStorage, GetVariable, Address, Nat, String } = require('@tezwell/smartts-sdk');
const SmartML = require('@tezwell/smartts-sdk/compiler');

const contract = new Contract()
.setStorage(Nat(0))
.addEntrypoint(
new EntryPoint('ep1').setInputType(TNat()).code((arg) => [
// Define a variable named "an_address"
NewVariable('an_address', Address('KT1R9M3MDffw7qSVSnbJs46aMC9YzzZz3aGT')),
// Require sender to be equal to variable "an_address", otherwise fail with "Not Admin!"
Require(Equal(GetVariable('an_address'), GetSender()), String('Not Admin!')),
// Replace the storage value with entry point argument
SetValue(ContractStorage(), arg),
]),
);

SmartML.compileContract(contract);
// Result:
// {
// micheline: 'parameter ...; storage ...; code { ... };',
// json: [
// { prim: 'storage', args: [...] },
// { prim: 'parameter', args: [...] },
// { prim: 'code', args: [...] },
// ]
// }
`

#### Build and compile a lambda

`js
const { Comparison, Lambda, If, Return, String, Nat } = require('@tezwell/smartts-sdk');
const SmartML = require('@tezwell/smartts-sdk/compiler');

// A Lambda that returns "YES" if the argument is greater than or equal to Nat(10), returns "NO" otherwise.
const lambda = Lambda()
.code((arg) => [
If(Comparison.GreaterThanOrEqual(arg, Nat(10)))
.Then([Return(String('YES'))])
.Else([Return(String('NO'))]),
]);

SmartML.compileValue(lambda);
// Result:
// {
// micheline: '{ PUSH nat 1; SWAP; COMPARE; GE; IF { PUSH string "YES" } { PUSH string "NO" } }',
// json: [
// {
// prim: "PUSH",
// args: [
// {
// prim: "nat"
// },
// {
// int: "10"
// }
// ]
// },
// {
// prim: "SWAP"
// },
// {
// prim: "COMPARE"
// },
// {
// prim: "GE"
// },
// {
// prim: "IF",
// args: [
// [
// {
// prim: "PUSH",
// args: [
// {
// prim: "string"
// },
// {
// string: "YES"
// }
// ]
// }
// ],
// [
// {
// prim: "PUSH",
// args: [
// {
// prim: "string"
// },
// {
// string: "NO"
// }
// ]
// }
// ]
// ]
// }
// ]
// }
