Though this vector is numeric, we can just as easily define a vector of strings, or even a vector of vectors. If the elements of a Vector have type $T,$ then the vector has type Array $\{T,1\}.$ Julia has a convenient type alias for one$-$dimensional arrays called Vector, so Array$\{T,1\}$ is equivalent to Vector $\{T\}.$

We can create a vector $x$ by listing comma$-$separated elements between square brackets $[$ and $]$:

$1x=[10,20,30,40,50]$

$5-$element Array Int$64,1\}$:

$10$

$20$

$30$

$40$

$50$

Julia also doesn't mind if we use semicolons to separate elements rather than commas:

$1y=[10$;$20$;$30$;$40$;$50]$
