lanqy / concat.array.buffers.js

Created March 28, 2021 14:42 — forked from 72lions/concat.array.buffers.js

Concatenates two ArrayBuffers

	/**
	* Creates a new Uint8Array based on two different ArrayBuffers
	*
	* @private
	* @param {ArrayBuffers} buffer1 The first buffer.
	* @param {ArrayBuffers} buffer2 The second buffer.
	* @return {ArrayBuffers} The new ArrayBuffer created out of the two.

	var _appendBuffer = function(buffer1, buffer2) {
	var tmp = new Uint8Array(buffer1.byteLength + buffer2.byteLength);

lanqy / eventemitter.js

Created May 12, 2019 16:10 — forked from mudge/eventemitter.js

A very simple EventEmitter in pure JavaScript (suitable for both node.js and browsers).

	/* Polyfill indexOf. */
	var indexOf;

	if (typeof Array.prototype.indexOf === 'function') {
	indexOf = function (haystack, needle) {
	return haystack.indexOf(needle);
	};
	} else {
	indexOf = function (haystack, needle) {
	var i = 0, length = haystack.length, idx = -1, found = false;

lanqy / regexCheatsheet.js

Created January 30, 2019 05:03 — forked from cxa/regexCheatsheet.js

A regex cheatsheet 👩🏻‍💻 (by Catherine)

	let regex;

	/* 匹配特定的字符串 */
	regex = /hello/; // 查找斜杠中的字符串（大小写敏感）……匹配 "hello", "hello123", "123hello123", "123hello"，但不匹配 "hell0", "Hello"
	regex = /hello/i; // 查找斜杠中的字符串（大小写不敏感）……匹配 "hello", "HelLo", "123HelLO"
	regex = /hello/g; // 全局查找斜杠中的字符串……

	/* 通配符 */
	regex = /h.llo/; // "." 匹配除了换行外的任何一个字符……匹配 "hello", "hallo"，但不匹配 "h\nllo"
	regex = /h.llo/; // "" 匹配任何字符零次或多次，如 "hello", "heeeeeello", "hllo", "hwarwareallo"

lanqy / regexCheatsheet.js

Created January 30, 2019 01:45 — forked from sarthology/regexCheatsheet.js

A regex cheatsheet 👩🏻‍💻 (by Catherine)

	let regex;

	/* matching a specific string */
	regex = /hello/; // looks for the string between the forward slashes (case-sensitive)... matches "hello", "hello123", "123hello123", "123hello"; doesn't match for "hell0", "Hello"
	regex = /hello/i; // looks for the string between the forward slashes (case-insensitive)... matches "hello", "HelLo", "123HelLO"
	regex = /hello/g; // looks for multiple occurrences of string between the forward slashes...

	/* wildcards */
	regex = /h.llo/; // the "." matches any one character other than a new line character... matches "hello", "hallo" but not "h\nllo"
	regex = /h.llo/; // the "" matches any character(s) zero or more times... matches "hello", "heeeeeello", "hllo", "hwarwareallo"
