Conversion

These methods exist on every value, converting between types. They return a new value.

.toStr() → string

Converts the value to its string form. Objects and arrays become JSON.

log (5).toStr()        // "5"
log { a: 1 }.toStr()   // {"a":1}

.toNum() → number

Parses/coerces to a floating-point number. Non-numeric strings become 0.

log "42".toNum()  // 42
log "3.5".toNum() // 3.5

.toInt() → int

Converts to an integer, truncating any fractional part.

log "42".toInt()   // 42
log (3.9).toInt()  // 3

.toBool() → boolean

Interprets the value as a boolean. true and the string "true" become true; everything else (including other strings and numbers) becomes false.

log "true".toBool()  // true
log "hi".toBool()    // false
log (1).toBool()     // false

This is a strict parse, not general truthiness. The condition in if/while uses ordinary truthiness instead (a non-empty string or non-zero number is true there).

.toArray() → array

Wraps or coerces the value into an array.

.toObject() → object

Coerces an object, array or JSON string into an object.

log "{\"a\":1}".toObject()  // {a: 1}

Length & type

.len → int

The length of a string, array or object. It is a property - no parentheses.

arr = [1, 2, 3]
log arr.len    // 3
log "hello".len // 5

Writing .len() with parentheses is an error. To get the type name of a value, use the typeof(value) function.
