  Hello Gordon,
  Thanks for teaching me. I will continue coding. :D

• jsvGetArrayLength return 1

  And, if I disabled NEOPIXEL and GRAPHICS in "board.py", how to calculate how many variables could be add to "variables" item, thanks.

  Hi,
  I would like to help Espruino enable to do more things, so I try to add other functions to it.
  But when I coding, jsvGetArrayLength return 1 all the time.
  Could anyone teach me for this, thanks.

  Here is the test code(added in the "jswrap_crypto.c"):

  JsVar *jswrap_crypto_test(JsVar* arr){
    printf("%d",jsvIsArray(arr)?1:0);
    //1
  
    printf("%d",jsvGetLength(arr));
    //1
  
    printf("%d",jsvGetArrayLength(arr));
    //1
  
    printf("%d",jsvGetChildren(arr));
    //1
  
    return NULL;
  }
  
  /*JSON{
    "type" : "staticmethod",
    "class" : "crypto",
    "name" : "test",
    "generate" : "jswrap_crypto_test",
    "params" : [
      ["arr","JsVarArray","An array"]
    ],
    "return" : ["JsVar","A string"]
  }
    this is a test function
   */
  

  And also copied from "jsvArrayJoin", and the while will run once.

  JsVar *jswrap_crypto_test(JsVar* arr){
    JsVar *str = jsvNewFromEmptyString();
    if (!str) return 0; // out of memory
  
    JsvIterator it;
    jsvIteratorNew(&it, arr, JSIF_EVERY_ARRAY_ELEMENT);
    JsvStringIterator itdst;
    jsvStringIteratorNew(&itdst, str, 0);
  
    while (!jspIsInterrupted() && jsvIteratorHasElement(&it)) {
      JsVar *key = jsvIteratorGetKey(&it);
      if (jsvIsInt(key)) {
        // add the value
        //JsVar *value = jsvIteratorGetValue(&it);
        //if (value && !jsvIsNull(value)) {
          //JsVar *valueStr = jsvAsString(value);
          //if (valueStr) { // could be out of memory
            //jsvStringIteratorAppendString(&itdst, valueStr, 0, JSVAPPENDSTRINGVAR_MAXLENGTH);
            //jsvUnLock(valueStr);
          //}
        //}
        //jsvUnLock(value);
        printf("h\n");
      }
      jsvUnLock(key);
      jsvIteratorNext(&it);
    }
    jsvIteratorFree(&it);
    jsvStringIteratorFree(&itdst);
    return str;
  }
  
  /*JSON{
    "type" : "staticmethod",
    "class" : "crypto",
    "name" : "test",
    "generate" : "jswrap_crypto_test",
    "params" : [
      ["arr","JsVarArray","An array"]
    ],
    "return" : ["JsVar","A string"]
  }
    this is a test function
   */
  

  After make, directly run on the Ubuntu 18.04, the test code is:

  require("crypto").test(new Array(1,2,3));
  

  Or

  require("crypto").test([1,2,3]);
