    chars const char16_t * A pointer to the string contains a input string.
    length size_t The length of bytes or chars, in characters.
    indexp size_t * In/Out parameter. A pointer to the lastIndex for the execution, and received the updated lastIndex.
    test bool Pass true to avoid creating match result array and store boolean value to rval.
    rval JS::MutableHandleValue Out parameter. Receives the result match result array or boolean value.

    Description

    JS_ExecuteRegExp and JS_NewRegExpObjectNoStatics execute the RegExp object, reobj, to the specified input string, chars, from *indexp index.

    If test is false, JS_ExecuteRegExp and JS_NewRegExpObjectNoStatics store the match result array to *rval if matches, otherwise stores null to *rval. If test is true, JS_ExecuteRegExp and JS_NewRegExpObjectNoStatics store the boolean value true to *rval if matches, otherwise stores null to *rval.

    JS_ExecuteRegExp updates the built-in RegExp object's properties.

    If successful, JS_ExecuteRegExp and JS_NewRegExpObjectNoStatics returns true and stores the result to *rval, otherwise returns false and the value of *rval is undefined
