arrayFilter

arrayFilter

> Functions

Returns a new list containing all the values of the source list array for which the callback function returned a value equivalent to true.

The callback function takes 1 to 3 parameters, in this order: (value, position, source list).

Example:

Parameters

• array: Source list.
• callback: Function called for each element.

Return

• newArray: New filtered list.

Note

• In LeekScript 1, null values are left in place of the removed values.
• In LeekScript <= 3, if the callback function takes one parameter, the value from the source list is sent; if it takes two parameters, the key and the value are sent.
