name: duk_concat

proto: |
|
|
void duk_concat(duk_context *ctx, duk_idx_t count);
|

stack: |
|
|
[ ... val1! ...! valN! ] -> [ ... result! ]
|
|
|
|
summary: |
|
|
<p>Concatenate zero or more values into a result string. The input values
|
|
are automatically coerced with
|
|
<a href="http://www.ecma-international.org/ecma-262/5.1/#sec-9.8">ToString()</a>.</p>
|
|
|
|
<p>This primitive minimizes the number of intermediate string interning
|
|
operations and is better than concatenating strings manually.</p>
|
|
|
|
example: |
|
|
duk_push_string(ctx, "foo");
|
|
duk_push_int(ctx, 123);
|
|
duk_push_true(ctx);
|
|
duk_concat(ctx, 3);
|
|
|
|
printf("result: %s\n", duk_get_string(ctx, -1)); /* "foo123true" */
|
|
duk_pop(ctx);
