It creates an array from key-value pairs. a[1] will be 2 and a[3] will be 4. Unspecified entries are default-initialized. It can be quite useful for building lookup tables.
Another reason why array initializers are different from array literals:
struct S{int a,b,c;}
S[] sarr = [{a: 1, b: 2, c: 3}, {a: 4, b: 5, c: 6}];
