A template for using the functions and variables in native Math object, without writing "Math." at the beginning, also "print" is the alias for "console.log"
(function(print, abs, acos, acosh, asin, asinh, atan, atanh,
atan2, ceil, cbrt, expm1, clz32, cos, cosh, exp, floor,
fround, hypot, imul, log, log1p, log2, log10, max, min,
pow, random, round, sign, sin, sinh, sqrt, tan, tanh,
trunc, E, LN10, LN2, LOG10E, LOG2E, PI, SQRT1_2, SQRT2) {

onurkerimov / setInterval-wrapper.js
Last active October 9, 2018 11:58
A practical setInterval function wrapper that I oftenly use, in which the interval is cleared when the callback function returns true.
(function() {
$.setInterval = function(int, fn) {
var returnValue
var interval = setInterval(function() {
if (returnValue === true) {
clearInterval(interval);
} else {
returnValue = fn()
}
}, int)

Open idea: parser combinator API using regex

This is my take on building a parser combinator library API in JavaScript. This library would have a very low surface area, and would be easy to learn for those who already know already know regex.

Parser combinators often create their own DSL (domain-specific language) to provide a less verbose way of declaring parsers. These DSLs have to support operators for things such as repetition, alternation, optionality, lookahead, and more. Some of them don't create DSLs and provide these as helper functions.

In the following link, there are JSON parser implementations done by several parser combinatiors/generators: https://chevrotain.io/performance/ Some of them are verbose, some of them are concise.

This parser combinator API I'm proposing will not provide a DSL, however it will result in very short parser declarations.
