Convert character to ASCII code in JavaScript

Question

How can I convert a character to its ASCII code using JavaScript?

For example:

get 10 from "\n".

Answer 1

"\n".charCodeAt(0); 

Answer 2

String.prototype.charCodeAt() can convert string characters to ASCII numbers. For example:

"ABC".charCodeAt(0) // returns 65 

For opposite use String.fromCharCode(10) that convert numbers to equal ASCII character. This function can accept multiple numbers and join all the characters then return the string. Example:

String.fromCharCode(65,66,67); // returns 'ABC' 

Here is a quick ASCII characters reference:

{ "31": "",      "32": " ",     "33": "!",     "34": "\"",    "35": "#",     "36": "$",     "37": "%",     "38": "&",     "39": "'",     "40": "(",     "41": ")",     "42": "*",     "43": "+",     "44": ",",     "45": "-",     "46": ".",     "47": "/",     "48": "0",     "49": "1",     "50": "2",     "51": "3",     "52": "4",     "53": "5",     "54": "6",     "55": "7",     "56": "8",     "57": "9",     "58": ":",     "59": ";",     "60": "<",     "61": "=",     "62": ">",     "63": "?",     "64": "@",     "65": "A",     "66": "B",     "67": "C",     "68": "D",     "69": "E",     "70": "F",     "71": "G",     "72": "H",     "73": "I",     "74": "J",     "75": "K",     "76": "L",     "77": "M",     "78": "N",     "79": "O",     "80": "P",     "81": "Q",     "82": "R",     "83": "S",     "84": "T",     "85": "U",     "86": "V",     "87": "W",     "88": "X",     "89": "Y",     "90": "Z",     "91": "[",     "92": "\\",    "93": "]",     "94": "^",     "95": "_",     "96": "`",     "97": "a",     "98": "b",     "99": "c",     "100": "d",     "101": "e",    "102": "f",    "103": "g",    "104": "h",    "105": "i",     "106": "j",    "107": "k",    "108": "l",    "109": "m",    "110": "n",     "111": "o",    "112": "p",    "113": "q",    "114": "r",    "115": "s",     "116": "t",    "117": "u",    "118": "v",    "119": "w",    "120": "x",     "121": "y",    "122": "z",    "123": "{",    "124": "|",    "125": "}",     "126": "~",    "127": "" }
