 ## mapPopulateSeries {#function-mappopulateseries}
 
 Syntax: `mapPopulateSeries((keys : Array(<IntegerType>), values : Array(<IntegerType>)[, max : <IntegerType>])`
 
-Generates a map, where keys are a series of numbers, from minimum to maximum keys (or `max` argument if it specified) taken from `keys` array with step size of one,
-and corresponding values taken from `values` array. If the value is not specified for the key, then it uses default value in the resulting map.
+Generates a map, where keys are a series of numbers, from minimum to maximum keys (or `max` argument if it specified) taken from `keys` array with step size of one, and corresponding values taken from `values` array. If the value is not specified for the key, then it uses default value in the resulting map.
 For repeated keys only the first value (in order of appearing) gets associated with the key.
 
 The number of elements in `keys` and `values` must be the same for each row.
 
 Returns a tuple of two arrays: keys in sorted order, and values the corresponding keys.
