The "everything" Javascript cheat sheet
I don't know how complete you're trying to be with "all syntax" but here are some holes I noticed in the data types section on a quick read through: Decimal without leading digit before decimal point: .1 Using + in exponential: 1.23e+3 Lowercase octal: 0o552 Sloppy octal: 0552 Uppercase hex: 0XF36A Escape sequences in strings "Face:\n\uD83D\uDE04" Tagged template literals: tag`Name: ${myName}` Octal/binary versions of bigint: 0o552n 0b10001101n ... RegExp objects: /abc/ Numeric keys in ordinary objects: { 1: "value" } String keys in ordinary objects: { "my key": "value" } Computed keys in ordinary objects: { [myKey]: "value" } Property shorthand in ordinary objects: { myValue } Methods in ordinary objects: { myMethod() { } } Special __proto__ key in ordinary objects: { __proto__: prototypeObject } Spread in ordinary objects: { ...value } (I would include get/set here but it looks like there is more about objects in another section that does mention get/set. I don't think I saw the other features above there, though) Spread in array objects: [ ...iterableValue ] Also with void, void 0 is typically used to represent undefined. And more typically the undefined global property which I think is worth mentioning even though its not strictly syntax. After all neither BigInt() nor Symbol() are syntax either. More on reddit.com

Object property keys can be named with variables! const key = 'foo'; const obj = { [key]: 'bar' }; console.log(obj.foo); // prints 'bar' Labeled statements. foo: for (let i = 0; i < 3; i++) { for (let j = 0; j < 3; j++) { console.log(`i: ${i} j: ${j}`); break foo; } }
