Looks like JavaScript, feels like Ruby, and it is a script language fitting in C programmers.

Here is 8 Queens puzzle algorithm.
var a = [], b = [], c = [], x = [];
var solution = 0;
const SOLUTIONMAX = 92;
function found(n) {
if (++solution < SOLUTIONMAX) return;
System.print("\nSolution %d\n" % solution);
for (var i = 0; i < n; i++) {
for (var j = 0; j < n; j++)
if (x[i] == j) System.print(" Q");
else System.print(" .");
System.print("\n");
}
}
function test(i, n) {
for (var j = 0; j < n; j++)
if (a[j] && b[i + j] && c[i - j + n - 1]) {
x[i] = j;
if (i < n - 1) {
a[j] = b[i + j] = c[i - j + n - 1] = 0;
test(i + 1, n);
a[j] = b[i + j] = c[i - j + n - 1] = 1;
} else found(n);
}
}
function nqueen(n) {
for (var i = 0; i < n; i++) a[i] = 1;
for (var i = 0; i < 2 * n - 1; i++) b[i] = 1;
for (var i = 0; i < 2 * n - 1; i++) c[i] = 1;
test(0, n);
}
nqueen(8);
