#destructure set the content of an array into different variables gotchas:- do not quote the array argument ( first agument ) it is important you quote the second argument to this function associative arrays work in alphabetical order use "," to separate the variables to assign each array element to
destrucutre array values
array=( bash ksh zsh )
destructre ${array[@]} "shell1,,shell2"
echo $shell1 > bash
echo $shell2 > zsh
destructure ${array[@]} "shell1,shell2,shell3"
echo $shell1 > bash
echo $shell2 > ksh
echo $shell3 > zsh
#... Spread a bunch of string inside an array
... string

#foreach foreach element of an array execute a function gotchas: dont'quote the array arugment ( i.e the first agument ) If you pass in a function as the callback using the function command you should wrap it in single quotes
s() { echo $(( $1 * $1 )) ;}
array=( 1 2 3 4 5 6 )
foreach ${array[@]} s
>>> 2 4 6 8 10 12
foreach ${array[@]} 'function s() { echo $(( $1 + $1 )) ;}' >> always end the function with a ( ;} )
>>> 2 4 6 8 10 12
#copyWithin copy an array index into another index quote the first argument use ${array[*]} instead of ${array[@]}
