Contains functions for JavaScript primitive operations.

js-any builtin

js-global js-any() js, global, unsafe

'self' in the browser or 'global' in node.js

subscript js-any(a js-any, key js-any) js, unsafe

Gets a property from a JS object. For a function call use call or call-property.

set-subscript void(a js-any, key js-any, value js-any) js, unsafe

Sets a property on a JS object.

call js-any(a js-any) js, unsafe

a() WARN: This does not await the result. WARN: subscript followed by call may not work. Use call-property instead.

call js-any(a js-any, arg js-any) js, unsafe

a(arg)

call js-any(a js-any, arg0 js-any, arg1 js-any) js, unsafe

a(arg0, arg1)

call js-any(a js-any, arg0 js-any, arg1 js-any, arg2 js-any) js, unsafe

a(arg0, arg1, arg2)

call js-any(a js-any, arg0 js-any, arg1 js-any, arg2 js-any, arg3 js-any) js, unsafe

a(arg0, arg1, arg2, arg3)

call-new js-any(a js-any) js, unsafe

new a()

call-new js-any(a js-any, arg js-any) js, unsafe

new a(arg)

call-new js-any(a js-any, arg0 js-any, arg1 js-any) js, unsafe

new a(arg0, arg1)

call-new js-any(a js-any, arg0 js-any, arg1 js-any, arg2 js-any) js, unsafe

new a(arg0, arg1, arg2)

call-property js-any(a js-any, name js-any) js, unsafe

a[name]()

call-property js-any(a js-any, name js-any, arg js-any) js, unsafe

a[name](arg)

call-property js-any(a js-any, name js-any, arg0 js-any, arg1 js-any) js, unsafe

a[name](arg0, arg1)

call-property js-any(a js-any, name js-any, arg0 js-any, arg1 js-any, arg2 js-any) js, unsafe

a[name](arg0, arg1, arg2)

call-property js-any(a js-any, name js-any, arg0 js-any, arg1 js-any, arg2 js-any, arg3 js-any) js, unsafe

a[name](arg0, arg1, arg2, arg3)

call-property-spread js-any(a js-any, name js-any, args js-any[]) js, unsafe

a[name](...args)

null js-any() js

undefined js-any() js

await js-any(a js-any) js, unsafe

typeof js-any(a js-any) js, unsafe

== bool(a js-any, b js-any) js, unsafe

This is actually JavaScript's === operator.

instanceof bool(a js-any, b js-any) js, unsafe

+ js-any(a js-any, b js-any) js, unsafe

eval js-any(source js-any) js, unsafe

Calls JavaScript's 'eval' function. 'source' should be JavaScript source code. This could be useful for making use of JS features that don't have a Keen analog, or if you just have a big chunk of JS code and don't have time to translate it to Keen.

This happens in its own scope, so don't count on anything being in the enclosing scope. Instead, eval a function literal, then call it, like "x => f(x)".eval call x. If appropriate, remember to make the function async and await the result.
