npm install moderate-code-interpreterModerate Code Interpreter is a basic interpreter that can run in the browser. It input is designed to be easily comprehensible for end-users, allowing them to understand the intended functionality of the code. Moreover, it is crafted to be straightforward enough for developer-adjacent roles, such as spreadsheet wizards, to swiftly create their own scripts. The grammar is designed with extensibility in mind, by priortizing essential functionality and having a rudimentary aesthetic to writing statements and expressions. Ideally domain-specific syntax could be layered atop of this core language.

Array Push
var a = [];
a += 1 + 2;
a += 3;
Complex Query
var a = query o in orders
filter all {
o.status == "paid";
o.items[?].id == "0120120";
} or all {
o.status == "pending";
}
list {
orderId: o.id,
status: o.status,
user: query u in users filter o.userId == u.id and u.id within 2 to 3 first u ,
itemIds: query i in o.items list i.id,
sum: query o in o.items aggregate (p, c) => p + c.cost,
... query o in o.items
aggregate {
stats: {
sum: (p = 0, c) => p + c.cost,

{k: {i: 3}},
{k: {i: 4}},
{k: {i: 5}},
{k: {i: 6}},
{k: {i: 7}}
];return query o in items
filter all {
o.k.i > 2;
o.k.i < 5;
}
list o;
Loop Statement
var i = 100000;
while( i > 0 ){
i -= 1;
}
Multiple Condition Expression
all {
1 < 2;
3 /2 < 3;
4 + 2 > 5;
}
Reference Assignment
