-## TypeScript Coding Style
-### Do not omit semicolons
-This is to avoid Automatic Semicolon Insertion (ASI) hazard.
-
-Ref:
-* https://www.ecma-international.org/ecma-262/#sec-automatic-semicolon-insertion
-* https://github.com/tc39/ecma262/pull/1062
-
-### Do not omit curly brackets
-Bad:
-``` ts
-if (foo)
-	bar;
-else
-	baz;
-```
-
-Good:
-``` ts
-if (foo) {
-	bar;
-} else {
-	baz;
-}
-```
-
-As a special case, you can omit the curly brackets if
-
-* the body of the `if`-statement have only one statement and,
-* the `if`-statement does not have `else`-clause.
-
-Good:
-``` ts
-if (foo) bar;
-```
-
-Make sure that the condition and the body statement are on the same line.
-
-### Do not use `==` when it can simply be replaced with `===`.
-🥰
-
-### Use only boolean (or null related) values in the condition of an `if`-statement.
-Bad:
-``` ts
-if (foo.length)
-```
-
-Good:
-``` ts
-if (foo.length > 0)
-```
-
-### Do not use `export default`
-This is because the current language support does not work well with `export default`.
-
-Ref:
-* https://basarat.gitbooks.io/typescript/docs/tips/defaultIsBad.html
-* https://gfx.hatenablog.com/entry/2017/11/24/135343
-
-Bad:
-``` ts
-export default function(foo: string): string {
-```
-
-Good:
-``` ts
-export function something(foo: string): string {
-```
