Parse Functions

Parse functions translate one class into another. Most parse functions, translate string into another class, such as integers or JSON structures.

parseInt(s, base)-> integer​

parse a string in the given base into a 64bit integer

if base is not given, it will default to 0

if the base argument is 0, the true base is implied by the string’s prefix (if present): 2 for "0b", 8 for "0" or "0o", 16 for "0x", and 10 otherwise.

let s = 10
parseInt(s) // return the int64 value of 10
parseInt(s, 2) // return the int64 value of 2

let s = "0b10"
parseInt(s) // return the int64 value of 2

parseFloat(s)-> float​

parse a string into a 64bit floating-point number

parseFloat("10") // return the float64 value of 10.0
parseFloat("10.11") // return the float64 value of 10.11

parseBool(s)​

returns the boolean value represented by the string.

it accepts 1, t, T, TRUE, true, True, 0, f, F, FALSE, false, False. Any other values returns undefined

parseBool("1") // return the bool value true  
parseBool("f") // return the bool value false  
parseBool("fa") // return undefined

parseJson(text) -> JSON​

parse a JSON string

return JsonObject, JsonArray, string, float, int, bool or null value
