The matrix strategy in GitHub Actions allows you to define a set of variables and their possible values. It creates a matrix of jobs, where each combination of the defined variables will result in a separate job being executed.
In the given code, thematrix strategy is used to define two variables: check and node. The check variable has two possible values: 'type:check' and 'format:check'. The node variable has two possible values: '18' and '20'. This means that a total of four jobs will be created, representing all possible combinations of the check and node variables.
This matrix strategy is useful when you want to run a set of jobs with different configurations or test against multiple versions of a dependency. It helps to reduce duplication in your workflow file and allows for efficient parallel execution of jobs.
