When submitting a job, the job id is outputted to standard output (stdout) as part of a long message, e.g.
$ sbatch --mem=10M hello_world
Submitted batch job 46
Although it possible to parse this output string to infer the job id, by adding option --parsable only the job id itself is outputted removing any needs for parsing, e.g.
$ sbatch --parsable --mem=10M hello_world
49
Using Bash syntax, you can capture the job id when submitting the job as:
$ job_id=$(sbatch --parsable --mem=10M hello_world)
$ echo "$job_id"
50
This allows you to pass it in downstream calls, e.g. sacct -j $job_id.
